File Handling
Hi,
Thanks a lot for your reply..But the code aint working. I tried the following command
perl -F '\|' -anle '$n=substr($F[1],2);print $_."|"x(42-$n)' Rej3.txt
Error: Can't open perl script "\|": A file or directory in the path name does not exist.
Here Rej3.txt is the name of the file. One more thing the FA* field(Reject count field ) is present as the seventh field in each record.
Also it will be great if you explain the meaning of each and every part in the command syntax. Thanks
