TMP and TEMP get redefined, but I need the original values
Sun Jun 12 17:56:00 GMT 2011
I don't update my Cygwin installation regularly, but recently I did, and
then a script of mine stopped working.
Looking for the cause I found out that the Cygwin maintainers chose to
redefine the TEMP and TMP environment variables in /etc/profile like this:
unset TMP TEMP
Before that change, the TMP and TEMP defined by Windows were used
unmodified (except for cygpath translation). I'm sure the maintainers
have good reasons for this change. However, now I'm unable to find out
the original TEMP setting from a script.
To help your imagination what this could be good for, the purpose of the
script in question is for aiding in Windows maintenance, specifically
for cleaning up the TEMP folder.
I helped myself by deactivating the lines cited above in /etc/profile
for now, but that is clearly not a fine solution. Well, I could store
the original values of TMP and TEMP in backup variables, like
WINDOWS_TEMP or so. That would have to go in /etc/profile before the
variables are unset. But then, this modification would probably get
overwritten the next time something is changed in that file on the
distribution side. (If it would not, I wouldn't have had the problem in
the first place.)
So, any ideas how this could be solved in a clean way?
