Really simple batch renaming in Linux
January 19, 2011 | 
Author While working on the photos section of trigonakis.com, I wanted to batch rename some photos, so after the renaming their new name would be prefix_i, where i is a incremental value. The following (stupidly) simple bash script provides the desired functionality:
#!/bin/bash INDEX=1 for i in *.$1; do echo item $INDEX: "$i" renamed to $2_$INDEX.$1 mv "$i" $2_$INDEX.$1 let INDEX=INDEX+1 done |
Usage:
#make the script executable chmod +x scriptname.sh #move the folder containing the files to be renamed mv from_path/scriptname.sh to_path/ #run the script ./scriptname.sh FILE_EXTENSION NAME_PREFIX #example: ./rnm.sh JPG photo |

New Weblog, First Post
Distributed Life
Welcome to Distributed Life blog. As the title suggests, this will be a technology (computer science mostly) related blog. My focus will be on Distributed Systems, since it is my area of interest, but I will also write some posts about Opera browser and generic technology/Internet topics that I find (extremely) interesting.
Topics’ Sources
The topics you will find here will be mostly drawn from my everyday (academic and not) experiences and from other interesting posts or sites that I meet. The Opera related topics will be focused so that they will explain to you why Opera browser is unique (don’t worry I won’t be biased towards Opera. I am the first to say that Opera still has some major problems..)
Posting Frequency
As I said, the posts will be drawn from interesting (or to be precise, from what I consider interesting :-P) topics, so the frequency that I will write new posts will vary from daily to weekly+. Anyaway, this weblog is not meant to be a generic tech one.. who needs one more of these!
Hope you will enjoy! Thank you for reading..
