Re: Renaming files with spaces in the name to files without spaces..
Sorry for this OT but I am trying for some hours to achieve a massive rename of files using a simple script and I have not success yet. I want to rename files like RESULTS OF JAN 01 2002.txt to RESULTS_OF_JAN_01_2002.txt i.e. all the spaces, being substituted by '_', and the last space being completely removed [yes it has a space after the suffix] I tried to experiment with sed/awk and creating a sample sh script with for i in 'ls' but the i takes values of 'RESULTS' 'OF' 'JAN'. This means that it doesnt take the full filename as value, but parts of the filenames. Can u please suggest an easy way to implement the massive rename? If you want to do it for all files in a directory: # for file in *; do mv $file `echo $file | sed -e 's/ /_/g'`; done should do the trick. I think Perl is overkill for something this simple. Someone else suggested tr, which probably works, but I've had more success with sed. But if you do this, won't the spaces be mistaken for filename separators? Try this instead - make sure you're using sh, not csh: ls *\ * | while read OLD ; do NEW=`echo $OLD | tr ' ' _` echo mv -i $OLD $NEW done This works because ls prints them on separate lines. Once you're sure that it will do the right thing, take out the echo and run it for real. If the files are all over the place, you can use find the same way: find * -name '* *' -type f | while read OLD ; do NEW=`echo $OLD | tr ' ' _` echo mv -i $OLD $NEW done You'll have to fix the directories separately (otherwise find gets lost).

Thank you all for your quick reply. I followed Rob's way and it was fairly easy to do. I had to change a bit something but it worked. The rename script that I used is: - --cut here-- #!/bin/sh ls *\ * | while read OLD ; do NEW=`echo $OLD | tr ' ' _` mv -i $OLD $NEW done - -cut here-- As u notice I had to add the semicolon in the $OLD variable because otherwise the mv was complaining. So this was a nice and fast way to do it. Thank you all people for your quick reply!! BigBrother - --- We are being monitored..but there is a solution...

No, he has quotes around his $file, and the `` part replaces spaces,
so this should work. Witness:
$ touch a b c
$ for i in *; do echo arg $i endarg; done
arg a b endarg
arg c endarg
Another solution is using a find awk combo, which makes it work
recursively (ie one commandline instead of one per directory):
$ find -d . -name '* *' | awk -F/ '{ OFS = /; o = $0; gsub( , _, $NF); print mv
\ o \ \ $0 \ }' | sh
This can probably be written in a shorter way by awk gurus, I'm just
trying to learn it and this was a good exercise, which is the reason
I'm replying to this post :)

Paste this into your shell:

YYY=${XXX%% }
ZZZ=$(echo ${YYY} | tr ' ' '_')
for III in $XXX $YYY $ZZZ; do
echo '$III'

No, he has quotes around his $file, and the `` part replaces spaces, so this should work. notice that $file is not enclosed in the sub shell (in between ``) as an argument to echo. if the $file happens to have end blanks, they will be eaten up. try... f=' p q r '; echo $( echo $f | sed 's/ /_/g' ) ...output /should/ have been '_p_q_r_', but is 'p_q_r'. $ touch a b c $ for i in *; do echo arg $i endarg; done ^ ^ ^ ^ arg a b endarg arg c endarg notice that you have enclosed the string to echo in double quotes, which preserves the spaces. - parv -- To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
