RE: regular expression search and replace

[Tristan M]

thats really handy especially for re-doing all the flag bits at once, is 
there a way to make it distinguish between, say ch->act and ch->comm so it 
only changes the act's and not the comm's?

And I'd just like to add my \s* into that regex, because a lot of people
put a space between the opening parentheses and their text, like
REMOVE_BIT( ch->act, PLR_WHATEVER ), and so with the regex below, you
run the risk of winding up with remove_bit(& ch->act, PLR_WHATEVER ),
but if you use:

perl -pe 's/REMOVE_BIT\(\s*/remove_bit(&/g' -i.BAK *.c

then that should compensate for any amount of whitespace... also, should
the ampersand be escaped? I know it had to be in vi in order to work
correctly, and regexes generally use that as an end-of-string marker
similar to the beginning-of-string ^ marker... Just 2 additional cents
:D

Actually if you do

perl -pe 's/REMOVE_BIT\(/remove_bit(&/g' -i.BAK *.c

it will automatically backup the files, appending a .BAK extension.
