Detecting the output stream type of a shell script

Question

I\'m writing a shell script that uses ANSI color characters on the command line.

Example: example.sh

#!/bin/tcsh
printf \"\\033[31m Succ         


        

Answer 1

See this previous SO question, which covers bash. Tcsh provides the same functionality with filetest -t 1 to see if standard output is a terminal. If it is, then print the color stuff, else leave it out. Here's tcsh:

#!/bin/tcsh
if ( -t 1 ) then
        printf "\033[31m Success Color is awesome!\033[0m"
else
        printf "Plain Text is awesome!"
endif
