I'm using using VSCode Remote SSH from my laptop (Linux) to work on projects that resides on a Linux host.
If I open an internal terminal in VSCode I can open files from the host by doing code some_file.txt. I frequently want to be able to do the same from terminals that are not originating from VSCode.
Is there anyway to open files in the VSCode-server while connected to a standard (Non VSCode internal) terminal?
From another StackOverflow answer, I learned that if you open an integrated terminal and find the VSCODE_IPC_HOOK_CLI environment variable, and set it to the same value in the non-integrated terminal, then run code from the code server install directory ~/.vscode-server, it will work. That article didn't mention that you can have more than one install in the ~/.vscode-server directory. The current install can be extracted from the VSCODE_GIT_ASKPASS_MODE variable, it looks like this:
$ echo $VSCODE_GIT_ASKPASS_NODE
/home/<user>/.vscode-server/bin/054a9295330880ed74ceaedda236253b4f39a335/node
Just chop off the node and add bin, and so run something like
$ /home/<user>/.vscode-server/bin/054a9295330880ed74ceaedda236253b4f39a335/bin/code myfile.txt
Edit:
Here is a small script that will connect the terminal to the latest created vscode window.
❯ cat ~/.local/bin/connect_vscode.sh
export PATH="${HOME}/.vscode-server/bin/$(ls -t1 ${HOME}/.vscode-server/bin | head -n 1)/bin:${PATH}"
export VSCODE_IPC_HOOK_CLI="$(ls -t1 /run/user/$(id -u)/vscode-ipc-* | head -n 1)"
# Tell tmux to set these variables for new windows/panes.
# Remove if you don't use tmux
tmux setenv PATH "$PATH"
tmux setenv VSCODE_IPC_HOOK_CLI "$VSCODE_IPC_HOOK_CLI"
None of the answers on this thread worked for me (due to more recent versions of VS-Code changing it's internal paths and I'm running a preview version).
I'm linking this similar/identical question+my solution:
VSCode Remote SSH doesn't open file from terminal
Hope it helps. 😉
C. R. Oldham's answer covers the technical detail of why/how.
If you want a 1-liner that works as an alias in your ~/.bash_profile:
# Open file in most recently-connected remote VSCode session.
alias code=$'VSCODE_IPC_HOOK_CLI=/run/user/`id -u`/$(ls -lt /run/user/`id -u`/ | egrep \.sock$ | head -1 | awk \'END {print $NF}\') `ls -lt ~/.vscode-server/bin/** | fgrep bin/remote-cli/code | head -1 | awk \'END {print $NF}\'`'

I have some files: file1.txt, file2.txt and I would like to rename them like this: file1.something.txt and file2.something.txt
I looked for some similar questions and I come up with this:
for i in file*.txt; do echo mv $i file*.something.txt; done
but unfortunately the output is:
mv file1.txt file*.something.txt
mv file2.txt file*.something.txt
and therefore only 1 file is created.
Could please somebody help?
(I am using a macbook air, I am not sure if this is relevant)
Thank you very much
Try this :
rename -n 's/\.txt/something.txt' *
(remove -n switch when your tests are OK)
There are other tools with the same name which may or may not be able to do this, so be careful.
If you run the following command (GNU)
$ file "$(readlink -f "$(type -p rename)")"
and you have a result like
.../rename: Perl script, ASCII text executable
and not containing:
ELF
then this seems to be the right tool =)
If not, to make it the default (usually already the case) on Debian and derivative like Ubuntu :
$ sudo update-alternatives --set rename /path/to/rename
(replace /path/to/rename to the path of your perl's rename command.
If you don't have this command, search your package manager to install it or do it manually
Last but not least, this tool was originally written by Larry Wall, the Perl's dad.
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

It is so confusing that emacsclient said it can't find socket just after executing emacs --daemon in bash:
$ ps aux | grep emacs
shiangro 1744 0.0 0.0 2432784 604 s000 S+ 1:03下午 0:00.00 grep emacs
$ /usr/local/bin/emacs --daemon
("emacs")
Starting Emacs daemon.
Restarting server
$ /usr/local/bin/emacsclient -t
emacsclient: can't find socket; have you started the server?
To start the server in Emacs, type "M-x server-start".
emacsclient: No socket or alternate editor. Please use:
--socket-name
--server-file (or environment variable EMACS_SERVER_FILE)
--alternate-editor (or environment variable ALTERNATE_EDITOR)
I have this settings in my .emacs:
(server-start)
(setq server-socket-dir "~/.emacs.d/server")
and it works,the server file ~/.emacs.d/server/server was just there,but emacsclient say it can't find socket,so annoying that I have to tell him the socket file using the -s option.
I find this thorny problem while I want let emacs runing as a daemon after everytime rebooting(start) systerm by using crontab's ◎reboot special strings.
In this case ,cron successfully started the emacs server and the server file ~/.emacs.d/server/server was also there, but later when I started a terminal and tried to emacsclient -t ,it failed and complained can't find socket file!
Although I can bypass this problem by using -s ~/.emacs.d/server/server everytime I excute emacsclient,or alias emacsclient as emacsclient -s ~/.emacs.d/server/server ,but is ther a better way to comfort my heart?
Backgroud:
system: Mac OS X 10.9.2
emacs: GNU Emacs 24.3.1 installed by homebrew
Finding the server socket file is the tricky bit, you can use lsof to find it, and then a bit of grep-ing to extract the socket path/filename.
lsof -c emacs | grep server | grep -E -o '[^[:blank:]]*$'
Or on OSX when you expect to be running /Application/Emacs you'd change the command name lsof is looking for with -c Emacs. ie.
lsof -c Emacs | grep server | grep -E -o '[^[:blank:]]*$'
You could use cut instead of the messy filtering grep (searching for non-blanks until the line end [^[:blank:]]*$)
lsof -c Emacs | grep server | cut -c70-
Better yet, squish the interspacing and use cut's field chopping.
lsof -c Emacs | grep server | tr -s " " | cut -d' ' -f8
Now that you have the socket (or it's empty) you can do a conditional start on emacsclient, ie.
#!/bin/bash
socket_file=$(lsof -c Emacs | grep server | tr -s " " | cut -d' ' -f8)
if [[ $socket_file == "" ]]; then
# Just run Emacs (with any arguments passed to the script)
# It would be a good idea to parse the arguments and clean/remove
# anything emacsclient specific.
# (ie. -e should be --eval for emacs)
# note that emacsclient doesn't fix these args for you either
# when using -a / --alternate-editor
emacs $# &
# or on OSX
/Application/Emacs.app/Contents/MacOS/Emacs $# &
else
emacsclient $# -n -s $socket_file
fi
Since you've done:
/usr/local/bin/emacs --daemon
the server is already started. So, you don't actually need the:
(server-start)
(setq server-socket-dir "~/.emacs.d/server")
in your .emacs. When you follow that approach, the server is placed in /tmp/emacs502 (or maybe some other number). On linux, emacsclient doesn't seem to have trouble finding it there (in that case I'm seeing /tmp/emacs1920), and so "emacsclient -nw" works. I'm trying it on OSX using HomeBrew, as you are, and I find I have to connect using:
emacsclient -nw -s /tmp/emacs502/server
(If you used --deamon=name, then you would use "name" instead of "server" in that last line.)
emacsclient only finds the emacs server if I run emacs from the command line. If I run emacs from the Ubuntu launcher then emacsclient fails to connect to the server.
If you want to use the Emacs daemon instead of the server, define the two environment variables
export ALTERNATE_EDITOR=""
export EDITOR=emacsclient
You can add these environment variables in either ~/.bashrc or ~/.profile.
If the ALTERNATE_EDITOR environment variable is empty, then Emacs will run its daemon and connect to it.
I think emacsclient can look for special file server in standard path only, e.g. in /tmp/emacs1000. If you change this parameter server-socket-dir, then you should tell about it to emacsclient by key -s.
I am using winCVS and I want to access the log file for commits in a repository so That I can search for a certain comment but i cant find the log file anywhere.
Where is it stored?
You could also use the cvs command directly, as in this answer:
cvs log -r BRANCHNAME | grep acomment
(you have grep command on Windows through Gow Gnu On Windows)
I have some issue with Internet connectivity in a LAN. Some users are happy and some complain about the Internet speed. So I came with an idea to install software on three different PCs and try to download/upload a file at the same time and record the speed. Then I will able to create a graph with the data that I acquired.
I am looking for a way to download several files and check the speed. I found How to grep download speed from wget output? for wget and sed. How do I use wget -O /dev/null http://example.com/index.html 2>&1 | sed -e 's|^.*(\([0-9.]\+ [KM]B/s\)).*$|\1|' for Windows? I already installed wget and sed on Windows.
All PCs running Windows XP or 7.
Sed isn't different on Windows. The only difference is, that /dev/null doesn't exist on Windows, but NUL.
So:
wget -O NUL http://example.com/index.html 2>&1 | sed -e 's|^.*(\([0-9.]\+ [KM]B/s\)).*$|\1|'
should work on Windows. I'm not 100% sure about 2>&1 - maybe there is some other syntax to use.
