There most certainly is "truncate" command in Linux:
TRUNCATE(1) User Commands
TRUNCATE(1)
NAME
truncate - shrink or extend the size of a file to the specified size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data
is lost.
If a FILE is shorter, it is extended and the extended part
(hole) reads
as zero bytes.
Mandatory arguments to long options are mandatory for short
options
too.
-c, --no-create

Hi Doug,--
At OS level, you can truncate the file using:
echo > filename.trc
or just
> filename.trc
Apparently there's a truncate command in Linux as well (but I've never used it).

Is there a way to manage the size of 12.2 ASM trace files? Several
trace files for gmon, lmhg, gen0 and mmon processes appear to keep
the same PID for the instance lifetime, resulting in very large
trace files. Setting MAX_DUMP_FILE_SIZE will prevent the trace
file from growing beyond the max size, but does this by not
logging new events to the files.
I'm looking for a way to trim or otherwise manage the size of
these files, which have open file handles so it is not as simple
as deleting or archiving them.
Thanks,
Doug
