what does sed 's!/!!' do?

[padaku]

hi can someone help me with above cmd...

[RobinVossen]

However I ain't really known with sed much. I guess it removes every / from the input and echos it back.

Since in Perl RegEx and by quickly poking in the Manual of sed I noticed that s is replace in RegEx.
! is the seperator.
Thus
s -> Replace
! -> seperator
/ -> To Replace
! -> seperator
<Nothing> -> Replace With
!-> seperator

However this is a really aimed guess you should read sed manuals to be 100% sure.

Cheers,
Robin
