Hi,
cat [filename] | awk '!/j\.k/ { print }'

Is that what you are looking for ?

Tom

What about grep -v '^j.k' test.txt ?

Or are you looking for more complex pattern matching?

Hi
If this pattern is alone on a line:
grep -v j.k

This is one way to do it.

#!/usr/bin/ksh
PATTERN=j.k
cat - << EOF | ed -s test.txt
/$PATTERN
d
w
q
EOF

# perl -ne '/j\.k/||print' infile

Off the command line:
sed -e '/j.k/d' test.txt

In a script:
#!/usr/bin/ksh

eval sed -e '/$1/' test.txt

#end script

Then invoke as ./script.sh j.k

Cheers

Oops...
#!/usr/bin/ksh

eval sed -e '/$1/d' test.txt

#end script

Then invoke as ./script.sh j.k

Was expecting a sed solution too.
