Currently, if you call scripts/gcc-version.sh without arguments it will
generate this output :
$ sh scripts/gcc-version.sh
scripts/gcc-version.sh: line 12: [: =: unary operator expected
scripts/gcc-version.sh: line 16: -E: command not found
scripts/gcc-version.sh: line 17: -E: command not found
0000
Not too pretty. I believe this is an improvement :
$ sh scripts/gcc-version.sh
Error: No compiler specified.
Usage:
scripts/gcc-version.sh <gcc-command>
