couldn't find a specific string on a variable containing file content
#!/bin/bash
core_pattern=$(cat /proc/sys/kernel/core_pattern)
apport_full_path="/usr/share/apport/apport"
if [[ $(grep "$apport_full_path" "$core_pattern") ]] ; then
echo "Found"
else
echo "Not Found"
fi
grep: |/usr/share/apport/apport %p %s %c %d %P: No such file or directory
Not Found
I expect an output of "Found" or "Not Found" but ending up with an error
If you want to store a file into a variable and then run grep, this approach is bit redundant:
#!/bin/bash
core_pattern=$(cat /proc/sys/kernel/core_pattern)
apport_full_path="/usr/share/apport/apport"
if grep -q "$apport_full_path" <<< "$core_pattern" ; then
echo "Found"
else
echo "Not Found"
fi
OR, better, run grep over the file itself, why to store to a variable:
#!/bin/bash
pattern_file="/proc/sys/kernel/core_pattern"
apport_full_path="/usr/share/apport/apport"
if grep -q "$apport_full_path" "$pattern_file" ; then
echo "Found"
else
echo "Not Found"
fi
Generally grep is used like:
grep <string to search> <file_to_seaarch>
or
grep <string_to_Search> <<< "${variable_to_search}"
