can someone help me? Have a H/w from my university. I have to put this 4 commands into 1:
grep - r - l 'TODO'
ln - s test *(It`s the name of file that I get after fisrt command)* softlink
grep -v -r -l 'TODO'
chmod 0644 lab *(It`s the name of file that I get after previous command)*
I tried to google this question but all I get was some stuff with ';' and '&'
But as I understood, it doens`t work in a proper way cause this commands are connected logicaly (I get the name of the file with which I have to work only after 'grep')

Could you elaborate a bit on what you are trying to do? It appears you are trying to search for a file with "TODO" in the file, then symlink that file to a file called "softlink". And finally change the permissions? Is that correct?

You can use the pipe '|' to use the output of the first command as the input for the second command like this:
# <first command> | <second command> ...

Could you elaborate a bit on what you are trying to do? It appears you are trying to search for a file with "TODO" in the file, then symlink that file to a file called "softlink". And finally change the permissions? Is that correct?
