Setting environment variables in Linux using Bash

Question

In tcsh, I have the following script working:

#!/bin/tcsh setenv X_ROOT /some/specified/path  setenv XDB    ${X_ROOT}/db setenv PATH   ${X_ROOT}/bin:${PATH}  xrun -d xdb1 -i $1 > $2 

What is the equivalent to the tcsh setenv function in Bash?

Is there a direct analog? The environment variables are for locating the executable.

Answer 1

export VAR=value will set VAR to value. Enclose it in single quotes if you want spaces, like export VAR='my val'. If you want the variable to be interpolated, use double quotes, like export VAR="$MY_OTHER_VAR".
