If I try to use Visual Studio Code (on macOS 10.15) to edit my crontab, it opens an empty file without the contents of my crontab.
$ VISUAL='code' crontab -e
crontab: no changes made to crontab
I didn't actually expect this to work (without -w) but include it for completeness. But when I add the -w it still fails.
$ VISUAL="code -w" crontab -e
crontab: code -w: No such file or directory
crontab: "code -w" exited with status 1
It occurred to me that there may be some weirdness with quoting, but neither single quotes nor the following fixed anything:
$ function codew() {
function> code -w "$1"
function> }
$ export VISUAL='codew'
$ crontab -e
The problem seems to be that the crontab's tempfile is not actually present. But how do I solve this? How can I use VS Code to edit crontabs?
Create a file touch ~/code-wait.sh:
#!/bin/bash
OPTS=""
if [[ "$1" == /tmp/* ]]; then
OPTS="-w"
fi
/usr/local/bin/code ${OPTS:-} -a "$#"
Make this file executable:
chmod 755 ~/code-wait.sh
Add to your .bashrc or .bash_profile or .zshrc:
export VISUAL=~/code-wait.sh
export EDITOR=~/code-wait.sh
Run command:
EDITOR='code' crontab -e
here the setting works for me.
.bashrc
## vscode
export VISUAL=/path/to/code-wait.sh
export EDITOR=/path/to/code-wait.sh
code-wait.sh
#!/bin/sh
code -w $*
That is quite a complex issue because there is no way to detect which tool calls the preferred editor. The TTY is the same and no environment variables can help.
Still, I was able to come up with a solution that enables the foreground mode (wait) for temporary files. IMHO, most if not all tools that use external editors and are waiting for them to save the file do use temporary files.
Full script is at https://github.com/ssbarnea/harem/blob/master/bin/edit but I will include here the main snippet:
#!/bin/bash
OPTS=""
if [[ "$1" == /tmp/* ]]; then
OPTS="-w"
fi
/usr/local/bin/code ${OPTS:-} -a "$#"
Is there a way to change the packaging mode of an existing JCR package from replace to update? As far as I know the packaging mode cannot be set in the AEM Package Manager dialogs.
What exactly would I have to do? Just change the filter.xml and repackage? Somehow, this didn't work for me. Am I missing something?
You'd have to change the filter.xml as well as the .content.xml in the definition subfolder.
Here is a small batchscript that unpacks, changes the mode and repacks a package.
If you save it as modPkg, you cann call it with two params:
modPkg FILENAME FITLERMODE
where FILENAME is the filename of the package and FILTERMODE should be merge, update or replace.
#!/bin/bash
filename=${1}
filterMode=${2}
echo "Extracting package."
jar xf $1
echo "Modifying filter.xml."
perl -pe 's|(root="[^\"]+")(( )*mode="[^\"]+"( )*)?(( )*(/)?>)|\1 mode="'"${filterMode}"'"\5|g' META-INF/vault/filter.xml > META-INF/vault/filter.xml.backup
rm -rf META-INF/vault/filter.xml
mv META-INF/vault/filter.xml.backup META-INF/vault/filter.xml
echo "Modifying .content.xml in definition-folder."
perl -pe 's|mode="[^\"]+"|mode="'"${filterMode}"'"|g' META-INF/vault/definition/.content.xml > META-INF/vault/definition/.content.xml.backup
rm -rf META-INF/vault/definition/.content.xml
mv META-INF/vault/definition/.content.xml.backup META-INF/vault/definition/.content.xml
echo "Repackaging."
jar -cfM ${filterMode}-${filename} META-INF jcr_root
echo "Deleting temp files."
rm -rf META-INF
rm -rf jcr_root
echo "Finished."
There might be more elegant ways to do the job, but it's easy enough.
I suppose I could compare the number of files in the source directory to the number of files in the target directory as cp progresses, or perhaps do it with folder size instead? I tried to find examples, but all bash progress bars seem to be written for copying single files. I want to copy a bunch of files (or a directory, if the former is not possible).
You can also use rsync instead of cp like this:
rsync -Pa source destination
Which will give you a progress bar and estimated time of completion. Very handy.
To show a progress bar while doing a recursive copy of files & folders & subfolders (including links and file attributes), you can use gcp (easily installed in Ubuntu and Debian by running "sudo apt-get install gcp"):
gcp -rf SRC DEST
Here is the typical output while copying a large folder of files:
Copying 1.33 GiB 73% |##################### | 230.19 M/s ETA: 00:00:07
Notice that it shows just one progress bar for the whole operation, whereas if you want a single progress bar per file, you can use rsync:
rsync -ah --progress SRC DEST
You may have a look at the tool vcp. Thats a simple copy tool with two progress bars: One for the current file, and one for overall.
EDIT
Here is the link to the sources: http://members.iinet.net.au/~lynx/vcp/
Manpage can be found here: http://linux.die.net/man/1/vcp
Most distributions have a package for it.
Here another solution: Use the tool bar
You could invoke it like this:
#!/bin/bash
filesize=$(du -sb ${1} | awk '{ print $1 }')
tar -cf - -C ${1} ./ | bar --size ${filesize} | tar -xf - -C ${2}
You have to go the way over tar, and it will be inaccurate on small files. Also you must take care that the target directory exists. But it is a way.
My preferred option is Advanced Copy, as it uses the original cp source files.
$ wget http://ftp.gnu.org/gnu/coreutils/coreutils-8.21.tar.xz
$ tar xvJf coreutils-8.21.tar.xz
$ cd coreutils-8.21/
$ wget --no-check-certificate wget https://raw.githubusercontent.com/jarun/advcpmv/master/advcpmv-0.8-8.32.patch
$ patch -p1 -i advcpmv-0.8-8.32.patch
$ ./configure
$ make
The new programs are now located in src/cp and src/mv. You may choose to replace your existing commands:
$ sudo cp src/cp /usr/local/bin/cp
$ sudo cp src/mv /usr/local/bin/mv
Then you can use cp as usual, or specify -g to show the progress bar:
$ cp -g src dest
A simple unix way is to go to the destination directory and do watch -n 5 du -s . Perhaps make it more pretty by showing as a bar . This can help in environments where you have just the standard unix utils and no scope of installing additional files . du-sh is the key , watch is to just do every 5 seconds.
Pros : Works on any unix system Cons : No Progress Bar
To add another option, you can use cpv. It uses pv to imitate the usage of cp.
It works like pv but you can use it to recursively copy directories
You can get it here
There's a tool pv to do this exact thing: http://www.ivarch.com/programs/pv.shtml
There's a ubuntu version in apt
How about something like
find . -type f | pv -s $(find . -type f | wc -c) | xargs -i cp {} --parents /DEST/$(dirname {})
It finds all the files in the current directory, pipes that through PV while giving PV an estimated size so the progress meter works and then piping that to a CP command with the --parents flag so the DEST path matches the SRC path.
One problem I have yet to overcome is that if you issue this command
find /home/user/test -type f | pv -s $(find . -type f | wc -c) | xargs -i cp {} --parents /www/test/$(dirname {})
the destination path becomes /www/test/home/user/test/....FILES... and I am unsure how to tell the command to get rid of the '/home/user/test' part. That why I have to run it from inside the SRC directory.
Check the source code for progress_bar in the below git repository of mine
https://github.com/Kiran-Bose/supreme
Also try custom bash script package supreme to verify how progress bar work with cp and mv comands

There is command progress, https://github.com/Xfennec/progress, coreutils progress viewer.
Just run progress in another terminal to see the copy/move progress. For continuous monitoring use -M flag.
cp -v -ur path/to/jsps/ /dest/path/
The above command copies all of the files that have been updated from the source directory to the destination, preserving the directory structure.
What I can't figure out is how to copy only *.someExtention files. I know that you can use something like:
find -f -name *.jsp -exec some awesome commands {}
But I don't know how to do it (and I don't have time to read the info pages in detail).
All help is greatly appreciated.
Thanks,
LES
If you want to use find / cp then the following should do the trick:
find -f -name *.jsp -exec cp --parents {} /dest/path \;
but rsync is probably the better tool.
rsync might help - you can tell it to just copy certain files with a combination of include and exclude options, e.g.
rsync -a \
--include='*.foo' \
--include='*/' \
--exclude='*' \
path/to/jsps/ /dest/path/
See the manual and look at the section entitled FILTER RULES for more.
I'm trying to tar up all the *.class files only on a Solaris box under a certain directory.
Reading the man pages for tar made it seem like the -I option is what I wanted.
This is what I've tried from the dir in question:
find . -name "*.class" >> ~/includes.txt
tar cvf ~/classfiles.tar -I ~/includes.txt
From that I get:
tar: Removing leading `/' from member names
/home/myhomedir/includes.txt
And the ~/classfiles.tar files is garbage.
I don't have write permission on the dir where the *.class files are so I need to have the tar written to my home dir. Could someone tell me where I have gone wrong? What tar magic should I use?
Check which tar you are running. That message about removing the leading slash is a gtar (GNU tar) message, and the -I option you are trying to use is a Sun tar option (which lives in /bin/tar).
(at least the above is all true on my Solaris machine)
