A simple Bash script for replacing all space characters in a string

[Telengard]

I had use for this today and decided to share it in case someone else needs something similar.

#!/bin/bash

count=0
name=""

for word in $@
do
    if [ $count -ge 1 ]
    then
        name+="_" # replacement character
    fi
    name+="$word"
    count=$((count + 1))
done
echo "$name"

Example:

$ ./repspc Space the final frontier
Space_the_final_frontier

This script has not been heavily tested so think twice about using it for mission critical applications. Please do add your comments, criticisms and improvements below.

Somebody said: "People who don't know UNIX are condemned to reinvent it... badly. "

tr " " "_"

echo "This is a test" | tr " " "_"

or

cat filename | tr " " "_"

Indeed, tr is one of many possible ways to solve the problem. But it is not a Bash script, nor is tr internal to Bash.

I wouldn't ever dream of calling what I did inventive either. I'm well aware that any programing problem I want to solve has already been solved better than I can do. That doesn't stop me from finding my own solutions in ways that work for me.
