Double quote filenames
Hi, I need to double quotes filenames in the following string:
Code:
      /tmp/*file1                                 /tmp/*file2                                 /tmp/*file3                                 /tmp/*file4

I tried to do this using sed, but it double quotes every character Smilie
Code:
$ echo "$files"|sed 's/^ */"/;s/ */" "/g;s/$/"/'
" """ "/" "t" "m" "p" "/" "*" "f" "i" "l" "e" "1" "/" "t" "m" "p" "/" "*" "f" "i" "l" "e" "2" "/" "t" "m" "p" "/" "*" "f" "i" "l" "e" "3" "/" "t" "m" "p" "/" "*" "f" "i" "l" "e" "4" ""

Any idea how to do this?

Does your input really look like that (no newlines)?

Code:
$ sed 's/[^ ][^ ]*/"&"/g' file1
      "/tmp/*file1"                                 "/tmp/*file2"                                 "/tmp/*file3"                                 "/tmp/*file4"

Add one more space in s/ */" "/g to make it s/ */" "/g.

Thanks for the help guys, both solutions work. But it doesn't solve my initial problem.

The variable I have containing the filenames needs to be used in a for loop:

Code:
for f in $files ; do
    do stuff
done

The problem is that the for loop evaluates the wildcard instead of parsing it.

This works, but not when these filenames are in a variable:
Code:
for f in "/tmp/*file1" "/tmp/*file2" "/tmp/*file3" "/tmp/*file4" ; do
    do stuff
done

Hmm. You did say it was a string, not a file!

Is it necessary to quote the filenames anyway? If the filenames have spaces in them then any given solution so far will fail anyway.

Code:
STR=$(echo $YourSrting | sed ...)

Code:
for FILE in $STR; do
  ...
done

One way:
Code:
files='      /tmp/*file1                                 /tmp/*file2                                 /tmp/*file3                                 /tmp/*file4'
set -f
a=($files)
set +f
for i in "${a[@]}"
do
 echo "$i"
done

producing
Code:
/tmp/*file1
/tmp/*file2
/tmp/*file3
/tmp/*file4

And yes, I did create some files in /tmp matching a couple of those globs.

It's kind of difficult to explain...
Let's say I have these files:
Code:
 
$ ls -1
1file1
1file2
2file1
2file2

My variable:
Code:
 
files="/tmp/test/*file1 /tmp/test/*file2 /tmp/test/*file3 /tmp/test/*file4"

If I loop through this using a for loop I get this:
Code:
 
$ for f in $files ; do echo $f ; done
/tmp/test/1file1
/tmp/test/2file1
/tmp/test/1file2
/tmp/test/2file2
/tmp/test/*file3
/tmp/test/*file4

Instead, I want this:
Code:
 
$ for f in $files ; do echo $f ; done
/tmp/test/*file1
/tmp/test/*file2
/tmp/test/*file3
/tmp/test/*file4

elixir_sinari, your solution works perfectly in bash but not in ksh unfortunately.
Is there any alternative which I can use with ksh?
