I have a script:
ENABLE_SYSLOG=true
test -r /etc/default/inotifywait && . /etc/default/inotifywait || exit 99
test -d $INOTIFY_FOLDER || exit 100
inotifywait -mrq -e ATTRIB --format '%w%f' "$INOTIFY_FOLDER" | while IFS= read -r FILE
do
if [ -f $FILE ];then
# If file
if [ `stat -c %a $FILE` != "664" ] ;then
CHMOD_LOG=$(chmod -v 664 "$FILE")
[[ "$ENABLE_SYSLOG" = true ]] && logger -t inotifywait -p user.info "$CHMOD_LOG" &
fi
else
# If directory
if [ `stat -c %a $FILE` != "2775" ] ;then
CHMOD_LOG=$(chmod -v 2775 "$FILE")
[[ "$ENABLE_SYSLOG" = true ]] && logger -t inotifywait -p user.info "$CHMOD_LOG" &
fi
fi
done
Why my condition
[[ "$ENABLE_SYSLOG" = true ]] && logger -t inotifywait -p user.info "$CHMOD_LOG"
Not work ?
If I remove
[[ "$ENABLE_SYSLOG" = true ]] &&
Then everything is fine.
I try to remove ampersand (&), try other condition (as you can see in example), try if instead of [[ - but all in vain.
Any condition is not work
[[ ... ]] is present in most advanced shells (ksh, bash, and zsh) but is missing in POSIX sh and in Ubuntu /bin/sh (which is a symlink to /bin/dash).
You can either replace [[ ... ]] with [ ... ] or test ... (both are equivalent, the second makes it clear that test is a command while [ ... ] appears as if it is special syntax), or (unless the script is explicitly invoked as sh FILENAME), start it with #!/bin/bash. Note that [[ ... ]] is parsed differently than test or [ ... ], as [[ is a reserved word, while [ and test are merely builtin commands. Specifically, field splitting and globbing are not done between [[ and ]], while = and == in this context do shell pattern matching if neither string is quoted. Furthermore, the =~ operator to do regexp matching is not present in test or [.

I use zsh and wrote a function to replace cd function. With some help I got it to work like I want it to (mostly). This is a followup to one of my other question.
The function almost works like I want it to, but I still have some problems with syntax highlighting and autocompletion.
For the examples, lets say your directories look like this:
/
a/
b/
c/
d/
some_dir/
I am also assuming the following code has been sourced:
cl () {
local first=$( echo $1 | cut -d/ -f1 )
if [ -d $first ]; then
pushd $1 >/dev/null # If the first argument is an existing normal directory, move there
else
pushd ${PWD%/$first/*}/$1 >/dev/null # Otherwise, move to a parent directory or a child of that parent directory
fi
}
_cl() {
_cd
pth=${words[2]}
opts=""
new=${pth##*/}
local expl
# Generate the visual formatting and store it in `$expl`
_description -V ancestor-directories expl 'ancestor directories'
[[ "$pth" != *"/"*"/"* ]] && middle="" || middle="${${pth%/*}#*/}/"
if [[ "$pth" != *"/"* ]]; then
# If this is the start of the path
# In this case we should also show the parent directories
local ancestor=$PWD:h
while (( $#ancestor > 1 )); do
# -f: Treat this as a file (incl. dirs), so you get proper highlighting.
# -Q: Don't quote (escape) any of the characters.
# -W: Specify the parent of the dir we're adding.
# ${ancestor:h}: The parent ("head") of $ancestor.
# ${ancestor:t}: The short name ("tail") of $ancestor.
compadd "$expl[#]" -fQ -W "${ancestor:h}/" - "${ancestor:t}"
# Move on to the next parent.
ancestor=$ancestor:h
done
else
# $first is the first part of the path the user typed in.
# it it is part of the current direoctory, we know the user is trying to go back to a directory
first=${pth%%/*}
# $middle is the rest of the provided path
if [ ! -d $first ]; then
# path starts with parent directory
dir=${PWD%/$first/*}/$first
first=$first/
# List all sub directories of the $dir/$middle directory
if [ -d "$dir/$middle" ]; then
for d in $(ls -a $dir/$middle); do
if [ -d $dir/$middle/$d ] && [[ "$d" != "." ]] && [[ "$d" != ".." ]]; then
compadd "$expl[#]" -fQ -W $dir/ - $first$middle$d
fi
done
fi
fi
fi
}
compdef _cl cl
The problem:
In my zshrc, I have a line:
zstyle ':completion:*' matcher-list 'm:{a-z}={A-Za-z}' '+l:|=* r:|=*'
This should make autocompletions case insensitive and make sure I can start typing the last part of a directory name, and in will still finnish the full name
Example:
$ cd /a
$ cd di[tab] # replaces 'di' with 'some_dir/'
$ cl di[tab] # this does not do anything. I would like it to replace 'di' with 'some_dir'
How do get it to suggest 'some_dir' when I type 'di'?
The second matcher in your matcher-list never gets called, because _cl() returns "true" (exit status 0, actually) even when it has not added any matches. Returning "true" causes _main_complete() to assume that we're done completing and it will thus not try the next matcher in the list.
To fix this, add the following to the start of _cl():
local -i nmatches=$compstate[nmatches]
and this to the end of _cl():
(( compstate[nmatches] > nmatches ))
That way, _cl() will return "true" only when it has managed to actually add completions.
I use zsh and I want to use a function I wrote to replace cd.
This function gives you the ability to move to a parent directory:
$ pwd
/a/b/c/d
$ cl b
$ pwd
/a/b
You can also move into a subdirectory of a parent directory:
$ pwd
/a/b/c/d
$ cl b/e
$ pwd
/a/b/e
If the first part of the path is not a parent directory, it will just function as normal cd would. I hope that makes sense.
In summary, when in /a/b/c/d, I want to be able to move to /a, /a/b, /a/b/c, all subdirectories of /a/b/c/d and any absolute path starting with /, ~/ or ../ (or ./).
I hope that makes sense.
This is the function I wrote:
cl () {
local first=$( echo $1 | cut -d/ -f1 )
if [ $# -eq 0 ]; then
# cl without any arguments moves back to the previous directory
cd - > /dev/null
elif [ -d $first ]; then
# If the first argument is an existing normal directory, move there
cd $1
else
# Otherwise, move to a parent directory
cd ${PWD%/$first/*}/$1
fi
}
There is probably a better way to this (tips are welcome), but I haven't had any problems with this so far.
Now I want to add autocompletion. This is what I have so far:
_cl() {
pth=${words[2]}
opts=""
new=${pth##*/}
[[ "$pth" != *"/"*"/"* ]] && middle="" || middle="${${pth%/*}#*/}/"
if [[ "$pth" != *"/"* ]]; then
# If this is the start of the path
# In this case we should also show the parent directories
opts+=" "
first=""
d="${${PWD#/}%/*}/"
opts+="${d//\/// }"
dir=$PWD
else
first=${pth%%/*}
if [[ "$first" == "" ]]; then
# path starts with "/"
dir="/$middle"
elif [[ "$first" == "~" ]]; then
# path starts with "~/"
dir="$HOME/$middle"
elif [ -d $first ]; then
# path starts with a directory in the current directory
dir="$PWD/$first/$middle"
else
# path starts with parent directory
dir=${PWD%/$first/*}/$first/$middle
fi
first=$first/
fi
# List al sub directories of the $dir directory
if [ -d "$dir" ]; then
for d in $(ls -a $dir); do
if [ -d $dir/$d ] && [[ "$d" != "." ]] && [[ "$d" != ".." ]]; then
opts+="$first$middle$d/ "
fi
done
fi
_multi_parts / "(${opts})"
return 0
}
compdef _cl cl
Again, probably not the best way to do this, but it works... kinda.
One of the problems is that what I type cl ~/, it replaces it with cl ~/ and does not suggest any directories in my home folder. Is there a way to get this to work?
EDIT
cl () {
local first=$( echo $1 | cut -d/ -f1 )
if [ $# -eq 0 ]; then
# cl without any arguments moves back to the previous directory
local pwd_bu=$PWD
[[ $(dirs) == "~" ]] && return 1
while [[ $PWD == $pwd_bu ]]; do
popd >/dev/null
done
local pwd_nw=$PWD
[[ $(dirs) != "~" ]] && popd >/dev/null
pushd $pwd_bu >/dev/null

pushd $1 >/dev/null # If the first argument is an existing normal directory, move there
else
pushd ${PWD%/$first/*}/$1 >/dev/null # Otherwise, move to a parent directory or a child of that parent directory

}

_cd

compadd "$expl[#]" -fQ -W "${ancestor:h}/" - "${ancestor:t}"
# Move on to the next parent.

done
else

compdef _cl cl
This is as far as I got on my own. It does works (kinda) but has a couple of problems:
When going back to a parent directory, completion mostly works. But when you go to a child of the paretn directory, the suggestions are wrong (they display the full path you have typed, not just the child directory). The result does work
I use syntax-hightlighting, but the path I type is just white (when using going to a parent directory. the normal cd functions are colored)
In my zshrc, I have the line:
zstyle ':completion:*' matcher-list 'm:{a-z}={A-Za-z}' '+l:|=* r:|=*'
Whith cd this means I can type "load" and it will complete to "Downloads". With cl, this does not work. Not event when using the normal cd functionality.
Is there a way to fix (some of these) problems?
I hope you guys understand my questions. I find it hard to explain the problem.
Thanks for your help!
This should do it:
_cl() {
# Store the number of matches generated so far.
local -i nmatches=$compstate[nmatches]
# Call the built-in completion for `cd`. No need to reinvent the wheel.
_cd
# ${PWD:h}: The parent ("head") of the present working dir.
local ancestor=$PWD:h expl
# Generate the visual formatting and store it in `$expl`
# -V: Don't sort these items; show them in the order we add them.
_description -V ancestor-directories expl 'ancestor directories'
while (( $#ancestor > 1 )); do
# -f: Treat this as a file (incl. dirs), so you get proper highlighting.
# -W: Specify the parent of the dir we're adding.
# ${ancestor:h}: The parent ("head") of $ancestor.
# ${ancestor:t}: The short name ("tail") of $ancestor.
compadd "$expl[#]" -f -W ${ancestor:h}/ - $ancestor:t
# Move on to the next parent.
ancestor=$ancestor:h
done
# Return true if we've added any matches.
(( compstate[nmatches] > nmatches ))
}
# Define the function above as generating completions for `cl`.
compdef _cl cl
# Alternatively, instead of the line above:
# 1. Create a file `_cl` inside a dir that's in your `$fpath`.
# 2. Paste the _contents_ of the function `_cl` into this file.
# 3. Add `#compdef cl` add the top of the file.
# `_cl` will now get loaded automatically when you run `compinit`.
Also, I would rewrite your cl function like this, so it no longer depends on cut or other external commands:
cl() {
if (( $# == 0 )); then
# `cl` without any arguments moves back to the previous directory.
cd -
elif [[ -d $1 || -d $PWD/$1 ]]; then
# If the argument is an existing absolute path or direct child, move there.
cd $1
else
# Get the longest prefix that ends with the argument.
local ancestor=${(M)${PWD:h}##*$1}
if [[ -d $ancestor ]]; then
# Move there, if it's an existing dir.
cd $ancestor
else
# Otherwise, print to stderr and return false.
print -u2 "$0: no such ancestor '$1'"
return 1
fi
fi
}
Alternative Solution
There is an easier way to do all of this, without the need to write a cd replacement or any completion code:
cdpath() {
# `$PWD` is always equal to the present working directory.
local dir=$PWD
# In addition to searching all children of `$PWD`, `cd` will also search all
# children of all of the dirs in the array `$cdpath`.
cdpath=()
# Add all ancestors of `$PWD` to `$cdpath`.
while (( $#dir > 1 )); do
# `:h` is the direct parent.
dir=$dir:h
cdpath+=( $dir )
done
}
# Run the function above whenever we change directory.
add-zsh-hook chpwd cdpath
Zsh's completion code for cd automatically takes $cdpath into account. No need to even configure that. :)
As an example of how this works, let's say you're in /Users/marlon/.zsh/prezto/modules/history-substring-search/external/.
You can now type cd pre and press Tab, and Zsh will complete it to cd prezto. After that, pressing Enter will take you directly to /Users/marlon/.zsh/prezto/.
Or let's say that there also exists /Users/marlon/.zsh/prezto/modules/prompt/external/agnoster/. When you're in the former dir, you can do cd prompt/external/agnoster to go directly to the latter, and Zsh will complete this path for you every step of the way.
I have a Scala application that I want to run inside a Docker container. To build the docker image, I use sbt-native-packager.
The base image I am using is "openjdk:8-jre-alpine".
Tried "openjdk:8-jdk-alpine" - does not make any difference
Tried sbt-native-packager 1.3.20 - does not make any difference
project/plugins.sbt
resolvers += Resolver.typesafeRepo("releases")
addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.3.17")
build.sbt
enablePlugins(JavaAppPackaging)
mainClass in Compile := Some("MyAppClass")
enablePlugins(DockerPlugin)
dockerBaseImage := "openjdk:8-jre-alpine" // startup fails with permission denied if using alpine :-(
Running a container with the resulting image leads to following error on startup:
docker run my-app:latest
docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"/opt/docker/bin/my-app\": permission denied": unknown.
ERRO[0000] error waiting for container: context canceled
The app starts up normally when using "openjdk:8-jre".

run the sbt task docker:stage. Then analyze the output created in the folder target/docker/stage.
In my case the Dockerfile contains the following:
FROM openjdk:11-jre-slim as stage0
WORKDIR /opt/docker
COPY opt /opt
USER root
RUN ["chmod", "-R", "u=rX,g=rX", "/opt/docker"]
RUN ["chmod", "u+x,g+x", "/opt/docker/bin/sample"]
FROM openjdk:11-jre-slim
LABEL MAINTAINER="your name"
USER root
RUN id -u demiourgos728 2> /dev/null || useradd --system --create-home --uid 1001 --gid 0 demiourgos728
WORKDIR /opt/docker
COPY --from=stage0 --chown=demiourgos728:root /opt/docker /opt/docker
EXPOSE 9000
USER 1001
ENTRYPOINT ["/opt/docker/bin/sample"]
CMD []
I had the problem that the PID file could not be created. I think in your case it will be something similar. There is no magic involved here.
The folder /opt/docker does not have write permissions by default. As the documentation states, you could add the following line to your build.sbt:
dockerAdditionalPermissions += (DockerChmodType.UserGroupWriteExecute, "/opt/docker")
which will add an additional line:
RUN ["chmod", "u=rwX,g=rwX", "/opt/docker"]
to the stage0 container. See nativer packager docs.
Alternatively, disable the PID file by passing a parameter to the JVM:
bashScriptExtraDefines ++= Seq( "addJava '-Dpidfile.path=/dev/null'" )
to your build.sbt. Play Production configuration Docs
I use these commands on a daily basis:
mkdir ______ && rar a -m0 -v200M ______/______.rar "XXXXXXXX" && rm -rf "XXXXXXXX" &&
par2 c -r10 -l ______/______.par2 ______/* && ~/newsmangler/mangler.py -c
~/.newsmangler.conf ______ && rm -rf ______
Where "XXXXXXXX" and "______" are two variables.
Is there a way to use a shortcut to make this easier since the only things that change are "XXXXXXXX" and "______"? I'm looking for something similar to:
mycommands _____ XXXXX
Couple things you may want to know:
- I use GNOME terminal.
- I don't have a root access.
Just write a function that accepts two arguments:
function just_do_it (){
( [ -z "$1" ] || [ -z "$2" ] ) && echo "No arguments given" && return 1
echo "do stuff with $1 and $2"
# notice to use double quotes, when processing the varibales
ls -l "$1"
}
The first line check if the two arguments are given. The argument can be accessed by $1 (first one) and $2 (second).
Edit: the function in your case would then for example look like this (a bit more readable formatted):
function just_do_it (){
( [ -z "$1" ] || [ -z "$2" ] ) && echo "No arguments given" && return 1
mkdir "$1" && \
rar a -m0 -v200M "$1/$1.rar" "$2" && \
rm -rf "$2" && \
par2 c -r10 -l "$1/$1.par2" "$1/*" && \
~/newsmangler/mangler.py -c ~/.newsmangler.conf "$1" && \
rm -rf "$1"
}
I have a directory with full svn backups named like this:
name1.20100412.r9.bz2
name1.20100413.r10.bz2
name2.20100411.r101.bz2
name3.20100412.r102.bz2
...
I need to check if a backup file exists using name and revision number only. I tried test but it didn't work:
if [ -e name1.*.r9.bz2 ]; then echo exists; fi
[: too many arguments
How can I test if file exists?
You could do:
shopt -s nullglob
set -- name1.*.r9.bz2
if [ -n "$1" ]; then echo exists; fi
or
pattern="name1.*.r9.bz2"
if [ "$(echo $pattern)" != "$pattern" ]; then echo exists; fi
Edit: Added shopt -s nullglob.
Just check if the shell has expanded the pattern. This works in sh and bash:
pattern="name1.*.r9.bz2"
if [ "$(echo $pattern)" != "$pattern" ]; then
echo exists
fi
P.S. If the pattern itself can be a valid filename, you can add a -e check:
if [ -e "$pattern" -o "$(echo $pattern)" != "$pattern" ]; then
echo exists
fi
A slight variation on eugene y's answer:
test "$(echo name1.*.r9.bz2)" != "name1.*.r9.bz2" && echo exists
I would use:
if ls name1.*.r9.bz2 &> /dev/null ; then
echo exists
fi
Try something like
FILES=(`ls name1.*.r9.bz2`)
if [ ${#FILES[#]} -gt 0 ]; then
echo "Files!"
else
echo "No Files"
fi

It seems to have a good answer, using the return value of ls.
