deleting a particular line in a file

[Henry Chua]

Hi Guys,

I am writing a script to remove a particular line in a file but it doesnt seem to work:

#!/bin/ksh


dline=`echo "henry_25"`
jfile=`echo "list"`

echo "jfile = $jfile"
echo "dline = $dline"

sed '/\$dline/d' $jfile > file
~

It appears that my identifier are not recognisable.. but if i need these identifier how can i alter the 'sed' command to achieve this? ThankS

regards
Henry

Hi Henry,

Woulnd a cat | grep -v "argument" >newfile do the job?


All the best

Hi,

In this case you have to use " (double quote) instead of ' (single quote)

sed "/$dline/d" $jfile > file
