Chet & Pierre: My apologies, the newlines were somehow removed by my email client. First, here's a properly formatted pastebin link:
http://pastebin.com/raw.php?i=AhF89GfT And here's another attempt at a properly formatted report: Configuration Information [Automatically generated, do not change]: Machine: x86_64 OS: linux-gnu Compiler: gcc Compilation CFLAGS: -DPROGRAM='bash' -DCONF_HOSTTYPE='x86_64' -DCONF_OSTYPE='linux-gnu' -DCONF_MACHTYPE='x86_64-pc-linux-gnu' -DCONF_VENDOR='pc' -DLOCALEDIR='/usr/share/locale' -DPACKAGE='bash' -DSHELL -DHAVE_CONFIG_H -I. -I../bash -I../bash/include -I../bash/lib -D_FORTIFY_SOURCE=2 -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -Wall uname output: Linux ubuntu 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Machine Type: x86_64-pc-linux-gnu Bash Version: 4.2 Patch Level: 45 Release Status: release Description: In a multi-line alias, where entries are separated by semi-colon, "source" commands are not executed in-step with all the other commands. After all the non "source" commands are executed, the "source" commands are executed in reverse order. See below for an example. Repeat-By: ubuntu@ubuntu:~$ cat script.sh #!/bin/bash (echo -n "$1 "; date +%S.%N) ubuntu@ubuntu:~$ alias foo1 alias foo1='~/script.sh one; source ~/script.sh two; source ~/script.sh three; ~/script.sh four' ubuntu@ubuntu:~$ alias foo2 alias foo2='~/script.sh one; source ~/script.sh two; source ~/script.sh three; ~/script.sh four; ' ubuntu@ubuntu:~$ foo1 one 09.742581873 two 09.745315889 three 09.749212492 four 09.761410711 ubuntu@ubuntu:~$ foo2 one 11.805819275 four 11.819741270 three 11.828260887 two 11.829470548 Fix: Use a single-line alias. Or use the "&&" operator to chain commands (which changes the functionality to be short-circuit evaluations). Also verified this behavior on RHEL6 with bash 4.1.2(1).
