Hi,
I just remembered "grep" use "--basic-regexp" as default.
Should we add "-F" and/or "-e" as soon as the following expression is not
using regexp or only when necessary?
=== 2 solutions: ===
- add -F or -e only when necessary
grep "string"
grep -e "-string"
grep -F "usb.usermap"
grep -Fe "-usb.usermap"
grep -Fe "-usb.usermap"
grep -Fe "${DUMMY_MSG}" (because $DUMMY_MSG may contains special chars)
grep "^string" (basic regexp)
grep -E "string2|string2" (extended regexp)
- always add -F -e
grep -Fe "string"
grep -Fe "-string"
grep -Fe "usb.usermap"
grep -Fe "-usb.usermap"
grep -Fe "-usb.usermap"
grep -Fe "${DUMMY_MSG}"
grep -e "^string" (basic regexp)
grep -Ee "string2|string2" (extended regexp)
I think that the second solution is better to avoid mistakes.
