Stupid spaces

Hello all,

I've done this before, but so long ago I can't find it again. I have a
bunch of files with spaces in them and I want to rename them with the
spaces removed.

I have a rename command that came with RH7.2 but doesn't do the job
rename 's/\ //g' *
does nothing in bash

So I wrote a script many moons ago to do this but I can't remember which
server it was on, let alone how I did it. Something with tr and mv methinks.

anyone?

The attached rename.pl is invaluable for such tasks.

Use it exactly like your bash rename attempt. You can use pretty much
any perl in-place-modifier construct - s/X/Y/, tr/A-Z/a-z/
(upper->lower), etc.

Not sure where I found this originally, but it's extremely handy.

Re: Stupid spaces

On RH, it does have a command 'rename', but not the way you used it.
Just type
rename ' ' '' *
couple of times to get rid of all the spaces

Oh! Hehe, looks like a DOS command. LOL

Very. Thanks. Not a BASH script, but works great.

Thanks.

Here you go, my simple aproach using the virtudes of bash scripting:

-- cut --
#!/bin/bash

DIR=$1
TOKEN="_"

cd $DIR;

# Here, we first wipe out spaces (actually, we replace them), otherwise
# a name like "my tex file.tex" would produce 3 elements, "my", "tex" and "file.tex"
for file in $(ls | sed -r 's/ /_:_/g'); do

new_name="$(echo $file | sed -r "s/_:_/$TOKEN/g")"
name="$(echo $file | sed -r 's/_:_/ /g')"

if [ -f "$name" ]; then
echo " Moving $name => $new_name"
mv "$name" "$new_name"
else
echo "$file does not exists (or element was not splited correctly in command: ls | tr ' ' ':' )"
fi

done

echo " done ..."
-- /cut --


Hope you find this usefull

rename doesn't work like DOS' rename, but:

rename old_pattern new_pattern files...

If you're lucky enough to have bash V2, use (faster):

for f in *;do mv -i "$f" "${f// /}";done

otherwise:

for f in *;do mv -i "$f" "$(echo $f|tr -d ' ')";done

If your actual intention of getting rid of spaces were
to get around difficulties in shell command globbing/parsing,
you should learn more about "find -print0" & "xargs -0" instead.

That's kinda what I was thinking, only problem with that is, the file named
"blah blah.p" will cause an error as bash/sh/ksh will think it is two files.
mv: cannot stat `blah': No such file or directory
mv: cannot stat `blah.p': No such file or directory

even tried using `ls -c1` same thing. Worse thing is I know I did this
before, so long ago, maybe I used Perl after all. Hmm...

Interesting. Only it doesn't "remove" the spaces it simply replaces them
with something else.

This last works, it also works in more then just bash so I like it best. I
have more then one OS that store Windows files for users. :)
I don't remember using echo in it last time but, it works...

Cheers.

Works for me, however I did forget to quote $x in original example.

[rich@deadrat ~/test]$ ls -l
total 0
-rw-rw-r-- 1 rich rich 0 Feb 13 09:19 blah blah.p
-rw-rw-r-- 1 rich rich 0 Feb 13 09:19 this is a test

[rich@deadrat ~/test]$ for x in *; do mv "$x" ${x// /_}; done

[rich@deadrat ~/test]$ ls -l
total 0
-rw-rw-r-- 1 rich rich 0 Feb 13 09:19 blah_blah.p

That would do it.
for x in *; do mv "$x" ${x// /}; done
removes the spaces, but only works in bash 2. :(

Re: Stupid spaces

well since we're all sharing space-removal tactics, here's my version: a
script i made to remove space (and other chars i dont like) from all files
in the current dir:
ls -1A > /tmp/desp.tmp
while read line
do
new=`echo -n "$line" | tr [:space:] _ | tr -d
[=\(=][=\)=][=]=][=[=][=!=][=\'=][=,=][=?=] | tr [:upper:] [:lower:]`
if [ "$new" = "$line" ] ; then
continue
fi
mv -i -- "$line" "$new"
done < /tmp/desp.tmp
rm /tmp/desp.tmp
