Shell Programming and Scripting

Hi
I have the following assignment in my ksh script:
PX_LIST="4119 2390 2294 2776 2897 4099"

Is there any sed/awk command which would allow the to remove certain number from this string. Let's say I need to remove PX=2390 from PX_LIST, so the output after deletion will be"
PX_LIST="4119 2294 2776 2897 4099"

The other lines in the file should not be changed, only value in PX should be removed from the string.

Thanks a lot for any help or advice. -A

Try this:

Code:

sed '/PX_LIST=/ s/2390 //' file

Regards

Franklin, thanks!
It works great for all the numbers except the last one. Is there a way to modify this command so the last number could be deleted as well. Thanks again -A

\< and \> for word boundary markers.

Code:

#!/bin/ksh

cat << EOF > file
PX_LIST="4119 2390 2294 2776 2897 4099"
EOF

search_num=4099

sed "/PX_LIST=/ s/\<$search_num\>//" file

search_num=2294

sed "/PX_LIST=/ s/\<$search_num\>//" file


### to get rid of extra spaces you can go:

search_num=2294
echo `sed "/PX_LIST=/ s/\<$search_num\>//" file`

Something like this?

Code:

sed '/PX_LIST=/ s/2390 //;s/\(.*\) .*/\1"/' file

Thanks a lot guys!!!! All the best to you
