That really isn't a flexible solution.

Code:
$ touch a.sh b.sh "c d".sh

$ ls -1
a.sh
b.sh
c d.sh

$ list=`ls *.sh`

$ echo $list | tr -s '\040' '\012'
a.sh
b.sh
c
d.sh

# whereas, ...
$ echo "$list"
a.sh
b.sh
c d.sh
# gives the correct output without tr

SYNOPSIS
bool touch (string $filename, [int $time = time()], [int $atime]) DESCRIPTION
Attempts to set the access and modification times of the file named in the $filename parameter to the value given in $time. Note that the access time is always modified, regardless of the number of parameters. If the file does not exist, it will be created. PARAMETERS
o $filename - The name of the file being touched. o $time - The touch time. If $time is not supplied, the current system time is used. o $atime - If present, the access time of the given filename is set to the value of $atime. Otherwise, it is set to the value passed to the $time parameter. If neither are present, the current system time is used. RETURN VALUES
Returns TRUE on success or FALSE on failure. CHANGELOG
