acctmerg reads its standard input and up to
250 additional files,
all in the tacct format (see
acct(FP))
or an ASCII version thereof.
It merges these inputs by adding records whose keys (normally user
ID and name) are identical, and expects the inputs to be sorted
on those keys.
Options are:
-a
Produce output in ASCII version of tacct.
-i
Input files are in ASCII version of tacct.
-p
Print input with no processing.
-t
Produce a single record that totals all input.
-u
Summarize by user ID rather than user ID and name.
-v
Produce output in verbose ASCII format,
with more precise notation for floating point numbers.
Examples
The following sequence is useful for making ``repairs''
to any file kept in this format:
