space in filename difficulty

I have a bunch of files that accidentally got written with a space in them:

301_A_L_mask _face.img
301_A_L_mask _scene.img
301_A_R_mask _face.img
301_A_R_mask _scene.img
302...
303...
etc.

How can I batch re-write these files to erase the space? For example,

301_A_L_mask _face.img -> 301_A_L_mask_face.img

Any help would be greatly appreciated!

Thanks,
David

Code:

for file in `ls *.img`

do

    $new_file=`echo $file |sed -e 's/ //'`

    cp "$file" $new_file

done

If that works, use 'mv' instead of 'cp'

Edit: as per ghostdog74's comment:
new_file=`echo $file |sed -e 's/ //'`
only use '$' when reading a bash var, not when writing to one (yeah, Perl is different)

Code:

for file in *.IMG

do  

  newfile=${file/ /}    

  mv "$file" $new_file

done

I feel very inellegant folks, a bit filename specific perhaps:

Code:

#!/bin/bash



> bashout

for file in $(ls -1 3[0-9][0-9]_A_[LR]_mask\ _*.img | tr -s " " "," )

do

  echo $file |

    awk '

    BEGIN {FS=","}

          { print ("mv " $1 "\\ " $2 " " $1 $2) } ' >> bashout

done



chmod 755 bashout

cat bashout

#./bashout

If the output looks ok then execute the bashscript written ./bashout or just remove the comment in the last line of the script above and run it again.

Whatever you do be safe.
