Check to see if a file exists?
Hi. I'd like to have an IF-Then-Else statement where I can check to see if a file exists? We have the Bourne Shell by default. I'm looking for the syntax to do something like this:
if myfile.txt exists then
...my code
else
...my code
end if
Any help would be greatly appreciated. Thanks.

exicyclog
EXICYCLOG(8) System Manager's Manual EXICYCLOG(8)
NAME
exicyclog - Cycle exim's logfiles
SYNOPSIS
eximcyclog
DESCRIPTION
The exicyclog script can be used to cycle (rotate) mainlog and rejectlog files. This is not necessary if only syslog is being used. Some
operating systems have their own standard mechanisms for log cycling, and these can be used instead of exicyclog if preferred.
Each time exicyclog is run the file names get 'shuffled down' by one. If the main log file name is mainlog (the default) then when exicy-
clog is run mainlog becomes mainlog.01, the previous mainlog.01 becomes mainlog.02 and so on, up to a limit which is set in the script, and
which defaults to 10. Reject logs are handled similarly.
If no mainlog file exists, the script does nothing. Files that 'drop off' the end are deleted. All files with numbers greater than 01 are
compressed, using a compression command which is configured by the COMPRESS_COMMAND setting in Local/Makefile. It is usual to run "exicy-
clog" daily from a root "crontab" entry of the form
1 0 * * * su exim -c /usr/exim/bin/exicyclog
assuming you have used the name 'exim' for the Exim user. You can run exicyclog as root if you wish, but there is no need.
