Working out time differences
Hi everyone,
I need to be able to write into a ksh script, a function that can look at 2 24 hour time variables and work out the difference between them.
e.g
job1 runs at 21:00
job2 runs at 01:00
diff = 04:00 hours
I would also need negative numbers i.e where job1 runs after job2
can anybody help?
cheers
Rik

Hi,
I'm writing a script and have become stuck trying to define a variable (COMP) by adding an elapsed time (ELAPSE e.g 00:55) to a start time (START e.g 23:50).
Can anybody give me a solution as to how I can get a completion time in hh:mm from the variables above?
thanks

envdir
envdir(8) System Manager's Manual envdir(8)
NAME
envdir - runs another program with environment modified according to files in a specified directory.
SYNOPSIS
envdir d child
DESCRIPTION
d is a single argument. child consists of one or more arguments.
envdir sets various environment variables as specified by files in the directory named d. It then runs child.
If d contains a file named s whose first line is t, envdir removes an environment variable named s if one exists, and then adds an environ-
ment variable named s with value t. The name s must not contain =. Spaces and tabs at the end of t are removed. Nulls in t are changed to
newlines in the environment variable.
If the file s is completely empty (0 bytes long), envdir removes an environment variable named s if one exists, without adding a new vari-
able.
EXIT CODES
envdir exits 111 if it has trouble reading d, if it runs out of memory for environment variables, or if it cannot run child. Otherwise its
exit code is the same as that of child.
