Full Discussion: Compare the content of a variable with a string

So you want to check that the file path contains a certain string?

Generally, you can do this by checking the exit status of the grep...

For example:

Code:
$ ( echo "${For_prp}" | grep "preuba.txt" >/dev/null 2>&1) && echo "Yes" || echo "No"
No
$ ( echo "${For_prp}" | grep "prueba.txt" >/dev/null 2>&1) && echo "Yes" || echo "No"
Yes

We can show this in an easier to understand form too:

Code:
echo "${For_prp}" | grep "prueba.txt" >/dev/null 2>&1
if [ "$?" -eq "0" ]; then 
  echo "Yes"
else
  echo "No"
fi

Cheers
