I submitted the job in the following different ways: 1) chgsum.pl AECCAR0 AECCAR2 resulted in "command not found" 2) chgsum.pl (AECCAR0) (AECCAR2)...resulted in "syntax error near unexpected token `AECCAR0' " 3) chgsum.pl (CHGCAR1) (CHGCAR2) (fact1) (fact2)....resulted in "syntax error near unexpected token `CHGCAR1' "
I used #! /usr/bin/perl script header using notepad. The vasp version i'm using is vasp.5.4.4.18 Apr17. So please experts give me your comments and suggestions for solving this problem.
Thank you in advance!
