shell script for converting filenames to proper case?


Hi,

Does anyone have a shell script to recommend to convert all files in a directory to proper case? (if the character previous to this is space, then capitalize, if not, set lower-case).

I assume there's a clever way to do this with bash+sed+awk, but with limited knowledge I do not even know where to start googling...

Thanks for any pointers or ideas... The ideal thing would be a bash function such as "convert_to_upper()" that took care of it

Hi and thanks for answering.

Good start, but this only converts lower to upper, not miXeD cAsE to Proper Case (first after space=CAPS - rest small)

Anyone?

Cool

Code:
#!/usr/bin/perl
# nicecase - proper case on icky filenames with spaces
foreach (@ARGV) {
  $was = $_;
  $_ = join ' ', map {ucfirst(lc($_))} split /\s+/, $_;
  rename($was,$_) or warn "Couldn't rename $was: $!";
}

bash script

Here is a pretty simple bash script


Code:
#!/bin/bash

for i in $@; do
  i=${i,,}
  echo -n "${i^} "
done
echo
Code:
> ./propercase abcdef ABCDEF aBcDeF AbCdEf abcDEF ABCdef
Abcdef Abcdef Abcdef Abcdef Abcdef Abcdef
>

You can also omit 'in $@' there. Nice code for bash 4.0.

Usually I am all for shortcuts, but I've found in instances like this, the second saved from omitting the 'in $@' usually leads to headaches down the road if the script is modified or used as a basis for a larger script.

What I do wish is there was a way to combine the two string functions into one, like
Code:
echo -n ${{i,,}^}

That doesn't really apply on my large scripts but well, that's an option.

Guess we can't do that in bash. Maybe in zsh.
