Modify files in a directory using perl
Closed - This job posting has been filled and work has been completed.
I am looking to have a perl script to modify a column in a series of files in a single directory. I am running v. 5.10.1.
the necessary changes are:
1. sequentially renumber the 4th column (based on the first column, restarting when it changes)
2. skip over rows that begin with MSH and do not write them out to the modified files
3. write files to a directory
Please see the attached for more information.
