need help with a Kornshell function

[ckrieger1]

I am trying to write a Kornshell function that takes a string parameter which represents a filename or directory name. The function checks to see if there are any spaces in the filename or directory name and then replaces the spaces with an underscore. The returned value is a filename or directory name without any spaces. Thanks for any suggestions you may have.

Example

$ f="hello world"
$ echo $f
hello world
$ f=`echo $f | sed 's/ /_/g'`
$ echo $f
hello_world

use the unix tr (translate) function
newfilename=$(print $filename | tr [' '] ['_'])

pretty sure that will work; don't have access to k-sh at this time.

Sometimes the grass is greener on the other side because there is more manure there - original.

The syntax for tr is :

[tt]newfilename=$(print "$filename" | tr ' ' '_')[/tt]

If you want to define a function :
[tt]
function ReplaceSpaces {
echo "$1" | tr ' ' "${2:-_}"
}
newfilename=$(ReplaceSpaces "$filename")
[/tt]
