Bash Scripting question
| Posted by mindbend, 04-04-2009, 01:38 PM | | I'm writing an inode and directory size counter, but hit a snag with directories that contain a space.
Simple code, finds all directories within a folder, sets the current directory:
for i in `find . -type d`; do ls $i; done
Looks correct? It works great, until you hit directories with spaces. So I try the following methods:
for i in `find . -type d|sed 's/ /\\ /g'`; do ls $i; done
for i in `find . -type d|sed 's/ /\\ /g'`; do ls "$i"; done
What is happening is, at the ( for i in ), it treats each item at the first break, if its \n or a ' '. Is there a flag I can set to make it only use \n? When I pipe the data, it sends each chunk of the directory through.
[root@home /home/mindbend/dev_html]# for i in `find . -type d|sed 's/ /\\ /g'`; do ls $i; done
ls: ./test: No such file or directory
ls: ing: No such file or directory
ls: 12: No such file or directory
ls: 3: No such file or directory
ls: ./test: No such file or directory
ls: ing: No such file or directory
ls: 12: No such file or directory
ls: 3/test: No such file or directory
ls: 2: No such file or directory
# ls -d test\ ing\ 12\ 3/
test ing 12 3/
#ls -d test\ ing\ 12\ 3/test\ 2/
test ing 12 3/test 2/
Any ideas?
GNU bash, version 3.2.39(1)-release (i386-portbld-freebsd7.1)

Issue exists on linux and freebsd, same code.

-=--
# IFS=$'\012'
# for i in `find . -type d`; do set -- $i; ls -d $i; done
.
./images
./images/nav
./test ing 12 3
./test ing 12 3/test 2
-=--
I'll post a link later to the entire inode counter script when I have completed it.
Thx for the reads!

find ./ -type d|while read i
do
ls -ld "$i"
done

| Posted by mindbend, 04-06-2009, 02:00 AM | Thx for the tip, I have tried it both ways and the processing speed appears to be close enough for a fast seek that both methods are feasible for this.
As promised in case anyone is interested, here is a quick script I whipped out ( freebsd ). The purpose of this script is to audit a directory tree to find inode/disk usage.
-=--
IFS=$'\012'; for d in `find . -type d`; do s=$(ls -AlF $d | grep -v / | awk '{ $5 = $5/1024; sum += $5; } END { print sum}') c=$(ls -AF $d|wc -l) ; printf "$c\t\t $s Kb\t\t\t\t - $d\n" >>usage; done ;
Output:
17 37.0977 Kb - ./dev_html
13 24.3496 Kb - ./dev_html/images
2 0.289062 Kb - ./dev_html/images/nav
27 238.59 Kb - ./dev_html/images-old
54 263.379 Kb - ./dev_html/images-old/cards
3 1.18945 Kb - ./dev_html/radmin
