Deleting the blank line in a file and counting the characters....
Hi,
I am trying to do two things in my script. I will really appreciate any help in this regards.
  • Is there a way to delete a last line from a pipe delimited flat file if the last line is blank. If the line is not blank then do nothing.....
  • Is there a way to count a word that are starting with "C" in the first column of a pipe delimited flate file.

Thanks a lot for help and time in this regards.

Raj

The count process is better done as:

Code:
grep -c "C" file1
Cheers!

Deleting the blank line in a file and counting the characters....
Thanks for replying on this.

I am sorry I potrayed the second part incorrectly. I need to count the letters for the words that starts with "C" in the first column in a pipe delimited file.

Something like:

C1213456| ---->this has 8 characters
C123|---->this has 4 characters

I have to pass this number to a variable.....

Thanks again for the time and help....
