-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I'm not a shell script pro and I don't know much about POSIX, but I have found this puzzling behavior in bash, and although it is documented I don't really understand why bash behaves this way. I was hoping someone could tell me. [EMAIL PROTECTED]:~$ set -H [EMAIL PROTECTED]:~$ echo "hi!" bash: !": event not found [EMAIL PROTECTED]:~$ echo "hi\!" hi\! This is somewhat unusual; generally, characters protected by backslashes are put through *unescaped*. Compare: [EMAIL PROTECTED]:~$ echo "\`" ` [EMAIL PROTECTED]:~$ echo "\"" " [EMAIL PROTECTED]:~$ echo "hi\$" hi$ The manual page does say explicitly, under "Quoting": The backslash preceding the ! is not removed. But no explanation is given for why this behavior exists. Is it part of POSIX compliance? An implementation detail?
