I have hundreds of files in a folder named transactions 1.csv, transactions 2.csv, transactions 3.csv etc

How do i remove the space in the file names, so they become transactions1.csv,transactions2.csv,transactions3.csv etc

Any help is appreciated?

With bash (and probably others) you can use ${f// /} to remove all spaces from $f:

for f in *.csv; do
    mv "$f" "${f// /}"
done

Also have a look at rename

rename ' ' '' *

but this only removes the first space, so it has to be applied several times.

  • @Thomas Erker - What web resource/book you recommend on learning about bash programming? – anonranger Sep 7 '15 at 15:58
  • @anonranger Sorry, can't really recommend anything. The Bash and sed & awk books from oreilly.com might be useful, but I haven't looked in them. – Thomas Erker Sep 7 '15 at 21:16
  • rename can remove all the spaces: rename "s/ //g" * or "s/ /_/g" etc. – tedder42 Jan 21 at 19:30
