how to delete record in file data with index in another file?
I want to deal with several data, i.e., data.*.txt with following structure
MSG|20010102|123 125 4562 409|SEND
MSG|20010102|120 230|SEND
MSG|20010102|120 204 5071|SEND
MSG|20010103|2 11 1098 9810|SEND
......

index file index.txt is
11
201
298
100
......

What I want to do is:
1) extract the record in index.txt
2) search it in data files $3, if this colomn contains the index number, then delete this record, else save without change

I have many questions:
1)Since each time I extract a record in index file, search it and delete records in data files, I have to save to original files for next index number. how can I save the file?
2) how to delete records using awk

i think it needs shell and awk scripts,
I try by myself, but i could not do any further.
while read record
do
awk ......
down < index.txt

thanks a lot.

git-fmt-merge-msg

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 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.

EXAMPLE

	   $ git fetch origin master
	   $ git fmt-merge-msg --log <$GIT_DIR/FETCH_HEAD

       Print a log message describing a merge of the "master" branch from the "origin" remote.
