I have found Notepad++ to be a great tool for Windows since it allows you to convert the line endings to Windows, Mac, or Linux while editing the file. It also has good code highlighting.

Iterate through a sparse array by using:

ARR=([0]=”zero” [1]=”one” [10]=”ten”)
for INDEX in ${!ARR[@]}
do
echo index $INDEX “=>” ${ARR[$INDEX]}
done

Oops., The easiest way to iterate is like you said initially., except you forgot the quotes:

for name in “${names[@]}”; do

works., and preserves the internal spaces in the elements…

as long as names are not separated by IFS (defaulting to white space).. for example

names=( “foo bar” “ben smith” )
for name in ${names[@]}; do echo “[${name}]“; done
[foo]
[bar]
[ben]
[smith]

whereas this preserves the spacing in array elements:

for ((i=0; i

Thanks for the for function m8, you just saved me some hours.
Now I can get back to my Script. You guys can also place the ‘do’ on the first line
IMHO it looks better this way.

for name in ${names[@]}; do

Right, I’ve forgot to mention that option too
If you are working on Ubuntu, like me, then the package “tofrodos” contains the dos2unix utility.
