Shell Programming and Scripting

I was trying to see all combinations of foreground and background colors in BASH.

This works fine for me,
echo -e '\E[37;46m TEXT'

but when I tried the below script, the variables i and j do not expand.

#!/bin/sh

for i in `seq 30 37` # foreground
do
for j in `seq 40 47` #background
do
echo -e '\E[$i;$jm TEXT'
tput sgr0 # Reset text attributes to normal without clear
done
done



I tried

echo -e "\E[$i;$jm TEXT"
echo -e '\E["'"$i"'";"'"$j"'"m TEXT'

no luck, please help.

Here you are not using bash.

yes porter, but anyway it does not work :-)

Hi,
try this
echo -e '\E['$i';'$j'm TEXT'

normally /bin/sh is a link to /bin/bash
if not sure, check out this
ls -las `which sh`
