the file gets filled with nulls thus increasing the size of the file.

Hi
I tried to empty an existing file (bring the size of the file down to 0). When I used “> myFile” or “cat </dev/null >myFile”, when I do a “ls –la”, the file size shows as 0.
I then wrote 540 lines to the file, and then opened it using vi, I see something like this:
"myFile" 540 lines,... (3 Replies)

rcsfreeze
RCSFREEZE(1L)RCSFREEZE(1L)NAME
rcsfreeze - freeze a configuration of sources checked in under RCS
SYNOPSIS
rcsfreeze [symbolic revision name]
DESCRIPTION
The rcsfreeze command has the purpose of assigning a symbolic revision number to a set of RCS files, which form a valid configuration.
The idea is to run rcsfreeze each time a new version is checked in. A unique symbolic revision number (C_number, where number is increased
each time rcsfreeze is run) is then assigned to the most recent revision of each RCS file of the main trunk.
If the command is invoked with an argument, then this argument is used as the symbolic name to freeze a configuration. The unique identi-
fier is still generated and is listed in the log file but it will not appear as part of the symbolic revision name in the actual RCS files.
A log message is requested from the user which is saved for future references.
The shell script works only on all RCS files at one time. It is important that all changed files are checked in (there are no precautions
against any error in this respect). Run rcsclean(1L) first and see whether any sources remain in the current directory.
FILES
[RCS/]rcsfreeze.version for the version number
[RCS/]rscfreeze.log for the log messages, most recent log message first.
