AWK - Question about sed

Question about sed

Raul B

2004-07-29, 3:55 pm

I have thousands of lines as:

TITLE = "Agent.Daily.AccessDenials", UNITS = "Runs",HISTORY_TIME =
"600", HISTORY_SPAN = 0, HISTORY_LEVEL = False,

Where I need to delete all the info that follows the "UNITS" match.

I wonder if there is a way to do this using sed or awk.

Any help would be very helpful.

Regards.

Raul.

Do you mean:
awk '/UNITS/{
match("^.*UNITS = \"[^\"]*\",$0)
print substr($0,1,RLENGTH)
}

It's easiest in sed:

sed 's/, UNITS =.*$//'

How about using the commas and deleting everything from the second
comma on:

sed 's/$[^,]*,[^,]*$.*/\1/' infile

But, of course, completely off topic for this newsgroup.

Thanks a lot four help, the solutions that says:

sed 's/, UNIT = .*$//'

was the simplest and the easiest.

Again thanks for your help.

sed 's/,.*//'

is simpler given what you seem to want.

Good point, maybe I could even redeem myself from earlier with a topical
response ;-):

awk -F, '{print $1}'

but I just can't resist a final OT one too:

cut -d, -f1

For the OP - questions about sed (or cut or any other non-awk tool) are
better directed to comp.unix.shell.

Sorry,

Ed.
