Restricting the merged file size to 1 GB
I am working on a problem in which I need to merge 4 files (say f1,f2,f3 & f4 log files) & then prepare a final file.

1) If the final file created has size more than 1 GB then need to throw error (display error).
2) Need to check after every merge (say f1 + f2, f1 + f2 + f3) that whether limit of 1 GB has been reached or not.

I am new to shell scripting, so I would appreciate the help.

Also, I need to write code for both UNIX & LINUX. What would be the difference in the code?

GIT-FMT-MERGE-MSG(1)						    Git Manual						      GIT-FMT-MERGE-MSG(1)

NAME

       git-fmt-merge-msg - Produce a merge commit message

SYNOPSIS

       git fmt-merge-msg [-m <message>] [--log[=<n>] | --no-log] <$GIT_DIR/FETCH_HEAD
       git fmt-merge-msg [-m <message>] [--log[=<n>] | --no-log] -F <file>

DESCRIPTION

       Takes the list of merged objects on stdin and produces a suitable commit message to be used for the merge commit, usually to be passed as
       the <merge-message> argument of git merge.

       This command is intended mostly for internal use by scripts automatically invoking git merge.

OPTIONS

       --log[=<n>]
	   In addition to branch names, populate the log message with one-line descriptions from the actual commits that are being merged. At most
	   <n> commits from each merge parent will be used (20 if <n> is omitted). This overrides the merge.log configuration variable.

       --no-log
	   Do not list one-line descriptions from the actual commits being merged.

       --[no-]summary
	   Synonyms to --log and --no-log; these are deprecated and will be removed in the future.

       -m <message>, --message <message>
	   Use <message> instead of the branch names for the first line of the log message. For use with --log.

       -F <file>, --file <file>
	   Take the list of merged objects from <file> instead of stdin.

CONFIGURATION

       merge.branchdesc
	   In addition to branch names, populate the log message with the branch description text associated with them. Defaults to false.

       merge.log
	   In addition to branch names, populate the log message with at most the specified number of one-line descriptions from the actual
	   commits that are being merged. Defaults to false, and true is a synonym for 20.

       merge.summary
	   Synonym to merge.log; this is deprecated and will be removed in the future.
