for name in `ls` and filenames with spaces
Replace
for name in `ls`
with:
ls | while read name
Notice: bash variable scoping is awful. If you change a variable inside the loop, it won't take effect outside the loop (in my version it won't, in your version it will). In this example, it doesn't matter.
Notice 2: This works for file names with spaces, but fails for some other strange but valid file names. See Charles Duffy's comment below.
Looks like two potential issues:
First, the IFS variable and it's assignment should not have space in them. Instead of
IFS = '\n' it should be IFS=$'\n'
Secondly, for name in ls will cause issues with filename having spaces and newlines. If you just wish to handle filename with spaces then do something like this
for name in *
I don't understand the significance of the line
number=`echo "$name" | grep -o "[0-9]\{1,2\}"`This will give you numbers found in filename with spaces in new lines. May be that's what you want.
