Assume that you were somehow able to generate this list. In real life problem, this would be couple hundred lines long (not just 3 lines). Call this listA. >> to >> >> 001_file2.txt >> 002_file3.txt >> 003_file1.txt > Call this listB. Let's see how listA can be changed to listB inside vim. $cat temp.txt file2.txt file3.txt file1.txt file5.txt file9.txt file10.txt file8.txt $cp temp.txt temp1.txt open temp1.txt in normal mode, put your cursor in line 1, column 1. Now enter the following letters. i001_<ESC>| qavf_yjPh<ctrl-a>|q [EMAIL PROTECTED] :w after this you should have temp1.txt as $cat temp1.txt 001_file2.txt 002_file3.txt 003_file1.txt 004_file5.txt 005_file9.txt 006_file10.txt 007_file8.txt $paste temp.txt temp1.txt > temp2.txt $cat temp2.txt file2.txt 001_file2.txt file3.txt 002_file3.txt file1.txt 003_file1.txt file5.txt 004_file5.txt file9.txt 005_file9.txt file10.txt 006_file10.txt file8.txt 007_file8.txt now open temp2.txt in normal mode in vim, put the cursor at line 1, column 1. enter the following commands <ctrl-v>G I mv <ESC> :w $cat temp2.txt mv file2.txt 001_file2.txt mv file3.txt 002_file3.txt mv file1.txt 003_file1.txt mv file5.txt 004_file5.txt mv file9.txt 005_file9.txt mv file10.txt 006_file10.txt mv file8.txt 007_file8.txt Voila! your script is ready. You can add #! /bin/sh at the top of temp2.txt and make it executable. It can be run by ./temp2.txt inside bash. Explanation of some of the vim commands. i001_<ESC>| insets 001_ and moves the cursor to the begining of the line. qavf_yjPh<ctrl-a>|q record some commands in register a. [EMAIL PROTECTED] execute the commands in register a, 5 times. If the number of files in listA is 100, you will do [EMAIL PROTECTED] instead of [EMAIL PROTECTED] :w write the file. hth raju -- Kamaraju S Kusumanchi http://www.people.cornell.edu/pages/kk288/ http://malayamaarutham.blogspot.com/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
