Question

I am using the bash following script to look for string in files:

find $1 -name "$2" -exec grep -Hn "$3" {} \;

Sometimes this script failed on

grep: /proc/sysrq-trigger: Input/Output error

In order to solve this I first think to exclude this file from the find result. is it a good idea and if yes how can I do that ? Is there any other solution to avoid my script failing ?

Answer 1

You can exclude all /proc directory in find like this:

find $1 -path /proc -prune -o -name "$2" -print -exec grep -Hn "$3" {} \;
