I was trying to remove some files and directories on my system but I didn't know so, I read about (wipe) command so, I thought that I may delete the files by it but I stopped the command running and when I tried open terminal again I did find this message at the beginning of CMD:
bash: /usr/bin/lesspipe: /bin/sh: bad interpreter: No such file or directory
so, please if anyone can help me anything instead of reboot or set up my system again I will be so appreciable.
To get
lesspipe
back you have to reinstall its package:
