Re: How can I do a quick scan and replace on an IFS file using CL?

I have a procedure that retrieves a file off a UNIX server onto the IFS.
I need to strip off the first character of the record if it is an 'S'.

*The* record? As in there is only one leading 'S' in the file?
Or *The first S of every record*?
Understanding that a Unix / stream file doesn't really have a concept of
'record' as we recognise it.

Is there an easy way to do this without having to import the file, strip the
character and then writing it back to the IFS?

I have sed and grep in both my PASE and QShell environments. It's been
so long that I'm not sure where I got them from. If I were starting out
now I'd probably hit up the YiPS:

out their chroot.

sed is only one way. Anything that can read stdin, run a regex and
write to stdout would work just as easily. Perl, PHP, and Python all
come to mind.

A completely untested regex off the top of my head:
find ^S(.*)
replace \1
With sed, that might look like sed -E "s/^S(.*)/\1/" < input > output
