Can't output desired string with "..." in bash??
Raw
bash_escaping.sh
#!/usr/bin/env bash
# This outputs "\$conf" as desired
echo $'s/^(\\$conf\\[\'simplesamlphp_auth_installdir\'\\] = .*)/if(whatever){ $1 } else { whatever };/'
# Yes, it can also be done with this craziness
echo 's/^(\$conf\['"'"'simplesamlphp_auth_installdir'"'"'\] = .*)/if(whatever){ $1 } else { whatever };/'
# But it doesn't seem to be possible with "..." ?
echo "s/^(\$conf\['simplesamlphp_auth_installdir'\] = .*)/if(whatever){ \$1 } else { whatever };/"
echo "s/^(\\$conf\['simplesamlphp_auth_installdir'\] = .*)/if(whatever){ \$1 } else { whatever };/"
