I have a perl script which can be used to ssh into a remote server using Net::SSH2, i need to search for a particular string over the files in a given directory in the remote system and print the given files in which the string occurs . Any ideas /sample codes on how i can go about this ?
Thanks
Solution proposed and accepted in the comments:
ssh <user>#<host> grep -d recurse -l <string> <directories>

I am trying to move all the *.csv files to another folder on server but every time i get access failed error , I am able to get all the files to local server using mget but mv fails everytime , i can see the file on the server and got full permissions on the files, sh script is not working with wild characters. struck here with the simple command .
Download to local directory
localDir="/home/toor/UCDownloads/"
[ ! -d $localDir ] && mkdir -p $localDir
#sftp in the file directory to be downloaded
remoteDir="/share/CACHEDEV1_DATA/Lanein1/Unicard/"
#The file to be downloaded is fileName
lftp -u ${sftp_user},${password} sftp://${host}:${port}<<EOF
PS4='$LINENO: '

mv "/share/CACHEDEV1_DATA/Lanein1/Unicard/"*.csv "/share/CACHEDEV1_DATA/Lanein1/Unicard/Archives/"
#rm /share/CACHEDEV1_DATA/Lanein1/Unicard/!(*.pdf)

This is not a shell or Bash problem. It is a LFTP problem.
From the manual of LFTP:
mv file1 file2
Rename file1 to file2. No wildcard expansion is performed.
LFTP just does not support what you asking for. It will treat *.csv as a part of the file name.
See here for an alternative.
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}\'`'
System: Arch Linux in VirtualBox 5.1.26 on Windows 10 Host
I try to use perl like sed in the terminal for in place substitution the input file:
perl -i -p -e 's/orig/replace/g' input_file
But I always get:
Can't remove input_file Text file busy, skipping file
This happens only if the file is inside a VirtualBox vboxsf share. With all other tools (sed, mv, vim or whatever) it is no problem to change the file.
This problem seems to be related to:
https://www.virtualbox.org/ticket/2553
https://forums.virtualbox.org/viewtopic.php?t=4437
I can't find any solution googling around :(
Update:
Using perl -i.bak -p -e 's/orig/replace/g' input_file I get a similar message:
Can't rename input_file to input_file.bak: Text file busy, skipping file.
This is exactly the same message as gedit shows:
So it is the same behavior, but googling around I can only find the Gedit topic. It seems noone has noticed this with perl -i.
While you are running a unix OS, you are still using a Windows file system. NTFS doesn't support anonymous files like unix file systems, and Perl -i requires support for anonymous files.
The workaround is to use a temporary files by using -i<ext> (e.g. -i~) instead of -i.
I have same problem. My solution is a bashscript. Copy files to tmp. Search and Replace. Overwrite tmp-files with original-files. Than delete tmp-dir. If you need you can use parameter in script for dynamic search&replace and create an alias for call the script direct and everywhere.
#!/bin/bash
echo "Removing text from .log files..."
echo "Creating tmp-dir..."
mkdir /tmp/myTmpFiles/
echo "Copy .log files to tmp..."
cp -v /home/user/sharedfolder/*.log /tmp/myTmpFiles/
echo "Search and Replace in tmp-files..."
perl -i -p0e 's/orig/replace/g' /tmp/myTmpFiles/*.log
echo "Copy .log to sharedfolder"
cp -v /tmp/myTmpFiles/*.log /home/user/sharedfolder/
echo "Remove tmp-dir..."
rm -vr /tmp/myTmpFiles/
echo "Done..."
I want to perform hundreds of video in our server to execute command like this one
flvtool2 -U video.flv
but the problem is I can't find any command to perform batch process.
is there a way to perform batch process?
thanks, TIA
also question can this be done in PHP execute command? thanks
I found the answer, with this command in ssh
ls -1 *.flv | while read file; do cat "$file" | flvtool2 -U stdin "$file" ; done
thanks to this link
http://michaelangela.wordpress.com/2008/06/30/how-to-add-duration-info-to-a-flv-file-with-the-flvtool2-command/
if you need this kind of command try it, it works on me :)
I have a bash code to backup my iOS files and send them to my website FTP in the directory: (http://mywebsite.com/sms) but when I run this code, it isn't .zip'ing the files and leaves the file 'zippyy.db' in the root of my website, not in the /sms folder.
I will be running this script from a few devices so when I execute the code, if there is already a file in the FTP called zippyy.zip, it will change it to zippyy1.zip, zippyy2.zip etc..
I would be really grateful for somebody to re-write the script for me. Thank you in advance! Here's my code:
#!/bin/bash
ROOTFOLDER="/var/root"
ZIPNAME="zipfolder"
ZIPFOLDER=$ROOTFOLDER/$ZIPNAME
LIBFOLDER="/var/mobile/Library"
ZIPFILE="zippyy.zip"
mkdir -p $ZIPFOLDER
cp $LIBFOLDER/SMS/sms.db $ZIPFOLDER/
cp $LIBFOLDER/Notes/notes.sqlite $ZIPFOLDER/
cp $LIBFOLDER/Safari/Bookmarks.db $ZIPFOLDER/
cp $LIBFOLDER/Safari/History.plist $ZIPFOLDER/
cd $ROOTFOLDER
zip -r $ZIPFILE $ZIPNAME
HOST=HOSTNAME
USER=USERNAME
PASS=PASSWORD
ftp -inv $HOST << EOF
user $USER $PASS
cd sms
dir . remote_dir.txt
bye
EOF
FILECOUNT=$(grep zippyy remote_dir.txt | wc -l)
NEXTDB="zippyy${FILECOUNT}.db"
mv $ZIPFILE $NEXTDB
ftp -inv $HOST << EOF
user $USER $PASS
put $NEXTDB
bye
EOF
You mean your archive is corrupt once it's been ftp'd?
Its likely your sending the file in default mode on your machine, which must be ASCII mode.
But first, on you local copy of zip file, issue the test option
zip -t $ZIPFILE
If that succeeds, then change you ftp here-doc to
ftp -inv $HOST << EOF
user $USER $PASS
binary
put $NEXTDB
bye
EOF
Note the addition of the ftp command binary, which means send file without translations for ASCII.
It's highly recommended to issue the following command
man ftp
And read through it at least once. Granted there are sections of even a good ftp man page that I have failed to find useful! ;-) . Also be aware that there are many ftp clients, with only a semblance of adherence to a common set of options, parameters and sub-commands. Don't assume that once you get it working at home, that it will work at the office, or at your friends place!
