[?] remove

[shyg]

Problem:
--------
I am trying to remove a userid and name from a file once the user has specified the userid or name to remove.

Sample Code:
------------
#!/bin/sh
echo Enter a userid or name to search for and remove:
read wrd
grep -w $wrd ~/test | cut $wrd

Notes:
------
Im using grep -w cause it returns the whole line containing both the usrid and full name depending on what the user searchs by. I wanted to pipe this through cut but I guess cut doesnt work on files in this way.

Try something like this:
sed -e "`grep -n -w $wrd ~/test | awk -F':' '{printf \"%dd;\",$1}'`" ~/test

Hope This Helps, PH.

Enter a userid or name to search for and remove:
britm
1:britm Brittney Morris

So, the script I posted should output the contents of ~/test without the first line, ie with userid removed.
your solution didnt work for me
Can you please be more specific on the unexpected behaviour ?

Ok when I run this and search by key word "Brittney", "Morris", or "britm" nothing is removed

Sample Code:
------------
#!/bin/sh
echo Enter a userid or name to search for and remove:
read wrd
sed -e "`grep -n -w $wrd ~/test | awk -F':' '{printf \"%dd;\",$1}'`" ~/test

All the test file is displayed, even the first line ?
To remove the line you have to do something like this:
sed -e "`grep -n -w $wrd ~/test | awk -F':' '{printf \"%dd;\",$1}'`" ~/test >tmp.$$ && mv tmp.$$ ~/test
