[net.unix] "sed" question

jwm@wucs.UUCP (John W. Matthews) (10/31/85)

Does anyone know of a way to put comments in a
"sed" script?  Failing that, does anyone know that
it is not possible to do so?

Please reply via E-mail as I do not monitor this group.

	The System V version of "sed" allows the first line of a
script to begin with a '#'; the line is treated as a comment.  The
4.2 BSD "sed" allows as many such lines as you care to sprinkle
throughout your script.

You could also use a kludge such as

/^$/s/Comment/ This is how one puts in comments??/

to put in additional comments in the System V version of "sed"
