Spaces in batch scripts
Since reading The Pragmatic Programmer I’ve become a bit of an automation junkie and writing batch scripts falls right under that category.
Unfortunately, nearly every single time I write one I forget that Windows really hates it when you have spaces in variable assignments, and I forget how to print out a usage message if the right number of parameters are not passed in.
So as much for me as for everyone else, this is how you do it:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
@ECHO off IF [%1]==[] GOTO usage IF [%2]==[] GOTO usage set VAR1=%1 set VAR2=%2 rem important client stuff goto end :usage echo Usage: script.bat var1 var2 :end echo Script finished |
