Top Forums Shell Programming and Scripting Check if 2 input values exists in a file Post 302957662 by Don Cragun on Tuesday 13th of October 2015 10:27:08 PM

Is this a homework assignment? (Note that homework assignments must be posted in the Homework and Coursework forum and must include a completely filled out homework template.)

Since there are no = characters in your sample input and there is no indication of how the value assigned to a is to be determined nor how the value of b is to be determined, and since you haven't even shown us what output you believe should be produced from your sample input there isn't much we can do without making lots of unsupported guesses.

NAME
svc, ci, co, svclog - shell version control system SYNOPSIS
ci [-lu] file co [-l] [-r rev] file svclog file OPTIONS
-l For ci, checkin, checkout again, and lock file -l For co, checkout file and then lock the archive -u After checking in, do not delete the file -r Check out revision rev instead most recent revision EXAMPLES
ci -u file # Check in file co -l file # Check out file and lock archive co -r 2 file # Check out version 2 DESCRIPTION
Svc is the Shell Version Control system, patterned on RCS. It maintains a sequence of versions in archive files, so that new versions can be checked in (added to the archive), and old versions can be checked out (made available). To create an archive for file, check it in with the -u flag. This action will prompt for a log message and then create an archive called file,S in the current directory, or in the subdirectory SVC if it exists. The file will not be deleted, but will be made unwritable. To update the file, check it out with the -l flag. Then modify it, and check it back in, giving a new message when prompted. After this process has been repeated many times, the archive will contain the entire history. Any version can be checked out using the -r flag. To get a printout of the history, use svclog. SVC(1)
