I have two Linux xterms with "almost" the same setup. One setup works and the other doesn't for my application.
Is there a tool that can help me figure out which particular environment variable is causing the failure? (A visual diff)
Currently - I do
env > a1
env > a2
in the 2 xterms and do a diff on them.
But would like to know if there is a tool which can help me save some time. Thanks
Putting together the comments of @msw and @Adam Byrtek (which I voted up) we get something like the following. Note that diff has a --side-by-side option that works well if you don't have X:
a1 $ env | sort > a1
a2 $ env | sort > a2
#somehow get the files on the same host
a2 $ meld a1 a2
# or, in a terminal setting
a2 $ diff --side-by-side a1 a2
Things to look for are PATH, LD_PRELOAD, and any APP vars like JAVA_HOME, PYTHON_PATH, or RUBYPATH.
