I was running a script normally. But suddenly, all the commands in the same line with sshpass started being not recognized. For instance:

sshpass -p "$password" rsync -a -e "ssh -o StrictHostKeyChecking=no -p $port" "$username@$hostname:${src_dir}${dir}/" "${dest_dir}${dir}/"

dirs=$(sshpass -p "$password" ssh -o StrictHostKeyChecking=no -p "$port" "$username@$hostname" "ls -lt --time-style=long-iso '$src_dir' | grep '^d' | head -n 3 | awk '{print $8}'")

These commands run (head,ls and the rest) successfully in other parts of the script. sshpass is installed:

atmos_username@atmosserver:~$ which sshpass
/usr/bin/sshpass

bash: grep: command not found bash: head: command not found bash: awk: command not found bash: ls: command not found rsync: connection unexpectedly closed (0 bytes received so far) [Receiver] rsync error: error in rsync protocol data stream (code 12) at io.c(231) [Receiver=3.2.7] Copying /mnt/ops/lap_ops/data/KASTOM_OUT/Tiff_files/20240529 to /home/sftp/life-sirius/uploads/Tiff_files/ bash: rsync: command not found

My OS is:

atmos_username@atmosserver:~$ lsb_release -a

  • Since I have to choose a site, which one do you think is more appropriate? I think Unix and Linux. Thanks.

  • I suspect you accidentally set PROMPT_COMMAND to a malformed command that tries to execute bash, head, awk etc in ~/.bashrc or somewhere else, what's the output of declare -p PROMPT_COMMAND?

    So far as I can see, the whole pipeline is being passed to the remote host - so you will need to look at the $username user's login bash shell on $hostname - most likely the PATH environment variable is set incorrectly

The problem was in the remote pc. In the bashrc file of the remote pc :

echo 'export PATH=/mnt/lap_c/home/ditsiaou/2023/.../...//sshpass/bin:/mnt/lap_c/home/ditsiaou/2023/.../.../' >> ~/.bashrc

source ~/.bashrc

echo 'export PATH=/mnt/lap_c/home/ditsiaou/2023/.../...//sshpass/bin:/home/d/ditsiaou' >> ~/.bashrc

source ~/.bashrc

Thanks for the help.
