The echo command looks too simple to cause trouble. But looks can be deceiving! The basic problem with echo is that there are two main forks of it and they are intrinsically incompatible. When printing anything that might be interpreted as an escape sequences it is better to use the 'printf' command. printf "%s\n" "\ttext" \ttext See this reference: http://www.opengroup.org/onlinepubs/009695399/utilities/echo.html It is not possible to use echo portably across all POSIX systems unless both -n (as the first argument) and escape sequences are omitted.
