The purpose of this page is to describe the function of
the clearcache command. When using a Web browser on
the Workstations at Maryland (WAM) or Glue systems (in the WAM/Glue Unix or WAM NT
environments); the web page source, including images, are stored
locally for fast retrieval in the local cache (pronounced
"cash") directory.
For the Firefox browser, the directory
is:
~/.mozilla/firefox/'random#'.default/cache
and for Internet Explorer, the directory could be in:
~/.ntprofile/Local Settings/Temporary Internet Files/Content.IE5
If you use both browsers interchangeably, both could exist.
These files build in size and can
eventually create a problem with respect to your quota, which
is currently 100 megabytes (100MB). Instead of deleting all the
cache files manually, you can run the command:
clearcache
The following message(s) will display on your monitor:
UNIX Firefox Cache Cleared
UNIX Mozilla Cache Cleared
UNIX Internet Explorer Cache Cleared
For example:
rac2:~: clearcache
UNIX Mozilla Cache Cleared
UNIX Internet Explorer Cache Cleared
rac2:~:
If you get the message "Command not found" when you run the
clearcache command, then type the following at
the command line:
/usr/local/scripts/clearcache
The same message(s) stating that Firefox and Internet
Explorer caches were cleared will appear.
Additionally, if you receive the "Command not found" message:
-
After the quota is less than 100%, log out and then
back into the account.
-
Run the
clearcache script again. If the system again gives a
"Command not found" message, you will need to reset the
default initialization files, as one may not be able to run
other general system scripts as well. You can do this by
typing the command:
/usr/local/scripts/newdefaults
-
This will replace any out-of-date login scripts (.login,
.cshrc, etc.) with the current system defaults. Any files
replaced will be copied to the same filename with the
current date appended, (like ".cshrc-99-12-14").
