how to handle file names with spaces in them
 

when i use this command

files =ls

any file or directories with spaces in them dont get saved properly in this variable.

like if have a directory named My Documents

only MY will be saved and God knows what happens to Documents.

so how do save the name of the whole document?

The trouble is that the spaces need to be escaped. I'm pretty sure the easiest way to do this in a script is to use sed with something like "sed s/ /\ /g". Since I'm new to sed myself bu haven't had a chance yet, to address this problem, I can't offer a working script. I can tell you that there is a perl script named "rename" that exists as a command on some Linux systems. It can be used to replace spaces with something else (e.g. underscore or just deleting the space). I believe it requires a similar syntax.

Hope this helps.

the problem is that this is a part of our assignment.

and our teacher wants to make life hell for us and wants that we deal with spaces in filenames and directories.

when the ls is piped into another command. only the first word is recorded in the variable.

#!/bin/bash
find . | while read FILE
do
#Now full name including spaces in $FILE
echo $FILE
done




HTH

buddy the bad thing is that our teacher has instructed us that any one using the find command will be given a zero

Oh stupid me, how could I not think of this. And the assignment itself is very secret, I suppose? Please take care not to be overly specific on it, since we here are all pretty eager to train our ability to read other peoples minds.

BTW you may tell your teacher that stuff like ls | grep | awk | ssh | mencoder | wine | finger | echo | halt is *very* bad style. Never do more than or two things in a single line, don't use a pipe if you can use a loop, and there is no need not to use 'find' if there is one. Always keep things simple and readable.

bahadur which school are you attending?

I would think you have to play with the Input File Separator env variable (IFS)

dear bahadur,

the solution is quite easy, u dont need sed or awk.
u can use the following command

ls -l|tr -s " "|cut -d " " -f x-

tr -s " " is used to suppress multiple spaces, so that u can use a single space in the cut command as your delimiter. now x is the column number from where the names of ur files start. thats it hope it solves ur problem. BTW u from india or what.

for file in *;do echo "[$file]";done[/b]

this catches spaces, newlines anything.

for file in *;do echo "[$file]";done

using `find` to access files with spaces in their names
 

thank you, Marius! I found my way here because I was trying to wax a windows installation on a laptop. the owner of the laptop wanted to make sure that no one could read her personal info, so I took your script and embellished a little.


boot knoppix and let it rip. maybe a couple times. of course, windows won't boot, but that's to be expected. it's not so fast, but I think it'll get the job done.

can u plz explain a little how ur code is working?

first, I'll say that it looks to me like you're asking us to do your homework for you. at the risk of sounding pedantic, you will learn more if you struggle with this stuff, and not just get the answers handed to you in a forum.

that said, knoppix is a linux distribution that boots from a CD. shove the disk in and restart the computer. very slick. knoppix allows you to mount the existing partitions that exist on the hard drive, and I have mounted the windows partition I'm wiping under /mnt/hda1.

in the script, the output of the find command is piped to the while loop. dd(1) and stat(1) have man pages.
