Hello,
I am trying, utilizing the few commands I know, to extract all records within my file that were generated in November of 2007. Each record within the file has a "date" field giving the month, day, and year (9-8-88). How do I extract those records to their own file?
Once I extract... (4 Replies)
How can I direct awk output to go nowhere? I can write the data to a file easy enough or print it on the screen. But for this particular command I don't actually want the data and I don't want to create a file. I just want the data discarded.
Thanks in advance (3 Replies)
Hello everyone, I've suddenly gotten very interested in sed and awk (and enjoying it quite a bit too) because of a large conversion project that we're working on. I'm currently stuck with a very inefficient process for processing text blocks. I'm sure someone here should be able to easily point out... (2 Replies)

What is the correct syntax to pipe or run three awk commands? Basically, using the output of the first awk as input in the second. Then using the output of the second awk in the third. Thank you :).

In the awk below the first sample MEV45 gets extracted from the html, but the subsequent MEV46 and MEV47 do not as they are not part of parse. I can not seem to add them to the code. Thank you very much @RudiC your awk is very nice :).

GIT-REFLOG(1) Git Manual GIT-REFLOG(1)NAME
git-reflog - Manage reflog information
SYNOPSIS
git reflog <subcommand> <options>
DESCRIPTION
The command takes various subcommands, and different options depending on the subcommand:
git reflog expire [--dry-run] [--stale-fix] [--verbose]
[--expire=<time>] [--expire-unreachable=<time>] [--all] <refs>...
git reflog delete ref@{specifier}...
git reflog [show] [log-options] [<ref>]
Reflog is a mechanism to record when the tip of branches are updated. This command is to manage the information recorded in it.
The subcommand "expire" is used to prune older reflog entries. Entries older than expire time, or entries older than expire-unreachable
time and not reachable from the current tip, are removed from the reflog. This is typically not used directly by the end users -- instead,
see git-gc(1).
The subcommand "show" (which is also the default, in the absence of any subcommands) will take all the normal log options, and show the log
of the reference provided in the command-line (or HEAD, by default). The reflog will cover all recent actions (HEAD reflog records branch
switching as well). It is an alias for git log -g --abbrev-commit --pretty=oneline; see git-log(1).
The reflog is useful in various git commands, to specify the old value of a reference. For example, HEAD@{2} means "where HEAD used to be
two moves ago", master@{one.week.ago} means "where master used to point to one week ago", and so on. See gitrevisions(7) for more details.
To delete single entries from the reflog, use the subcommand "delete" and specify the exact entry (e.g. "git reflog delete master@{2}").
OPTIONS --stale-fix
This revamps the logic -- the definition of "broken commit" becomes: a commit that is not reachable from any of the refs and there is a
missing object among the commit, tree, or blob objects reachable from it that is not reachable from any of the refs.
This computation involves traversing all the reachable objects, i.e. it has the same cost as git prune. Fortunately, once this is run,
we should not have to ever worry about missing objects, because the current prune and pack-objects know about reflogs and protect
objects referred by them.
--expire=<time>
Entries older than this time are pruned. Without the option it is taken from configuration gc.reflogExpire, which in turn defaults to
90 days.
--expire-unreachable=<time>
Entries older than this time and not reachable from the current tip of the branch are pruned. Without the option it is taken from
configuration gc.reflogExpireUnreachable, which in turn defaults to 30 days.
--all
Instead of listing <refs> explicitly, prune all refs.
--updateref
Update the ref with the sha1 of the top reflog entry (i.e. <ref>@{0}) after expiring or deleting.
--rewrite
While expiring or deleting, adjust each reflog entry to ensure that the old sha1 field points to the new sha1 field of the previous
entry.
--verbose
Print extra information on screen.
