vile's running in a terminal. I'd check if the terminal is configured for color: disregarding hard-coded stuff, the value of $TERM is used to select a terminal description. If it's "vt100" on some machines, that would explain. Running this from the command-line will show colors only if the terminal is configured: #!/bin/sh tput blink tput bold tput setab 1 tput setaf 4 printf "Hello-" tput setaf 1 tput setab 4 echo "world" tput sgr0 read aa -- Thomas E.
