10.0.0.21 <-- duplicated...

I want to append matched output and cat the results into an variable. but I've been running into problems. sed is printing result on to screen instead of appending the output to $CAPTURE. I'm...

Thanks! You're the man!

hi! could you explain the differences between /usr/bin/grep and /usr/xpg4/bin/grep? will there be any script portability issue?

and would it correct to map it this way?

hi guys,

would appreciate some help here. I need to append running numbers using sed onto a variable that contain a list of IP addresses. I'm basically stuck on the running number part. e.g.

1....

This is my file now:

1 June 3 10:30:22 test 1
1 June 3 10:34:22 test 4
1 June 3 10:35:22 test 5

Hi guys! Thanks for your help! I've made the following changes..funny thing is that grep still doesn't run

#!/bin/sh
TEST=test.log
GREP=/usr/bin/grep

eval "$GREP -i 'dog\|cat' ${TEST}"

And...

#!\bin\sh
TEST=test.log
GREP=\usr\bin\grep

$GREP -i 'dog\|cat' ${TEST}

Why doesn't grep run at all?

remove the "-n" from
TAIL="/usr/bin/tail -n"

Hi guys...

What am I doing wrong?

#!/bin/sh
LINES=1
FILE=test.log
TAIL="/usr/bin/tail -n"

$TAIL -${LINES} ${FILE}

Error:

./tail.sh
usage: tail [+/-[n][lbc][f]] [file]
