one way

Code:

echo "$somevar" | grep -q  '-rw-r--r--'
if [[ $? -eq 0 ]] ; then
     echo "found"
else
     echo "not found"
fi

This matches -rw-r--r-- any position inside the somevar variable.

However if you are looking for files in a directory with specific permissions, consider using

Code:

find dir_to_search -perm [perms you want]  -print

This is a better approach. Read your find man page, the section on -perm
