Sed does, but ksh will beep and not accept the tab:
Code:
$ cat dummy
#!/bin/sh
exit
$ sed 's/\//\/g' dummy
sed: 1: "s/\//\/g": unterminated substitute in regular expression
$ csh
celeron:bin {1} sed 's/\//\ /g' dummy
#! bin sh
exit
celeron:bin {2}
Only trust man pages. Trust? As long as you now under which shell the author wrote his code or examples.

Dumb me!
tab is the autocompletion key in bash, ksh, .... 'course it beeps!
