OK, I understand the idea. Is there a way for me to use the record number that was previously entered by the user (the code in my last post)?
Here's what I just tried, but it completely overwrote the file with a blank file.
I would like to completely remove the record and put the new data in its place.
I am really lost I don't know what this line does. Please help I'm very lost. Thanks in advance.
cat CPROGRAMS.c
|sed 's// /g'|tr ' ' '\012'
|grep ''
|sed 's/^*/ /'
|grep '($'|sort -u|tr -d "("` (4 Replies)
