A command line tool for filtering (sifting) the results of a command that has been run typically under cron, but could be used elsewhere.
Use the 'go get' command to download the package.
go get github.com/outtenr/cronsifter
To install:
go install github.com/outten45/cronsifter/cmd/...
This will create the cronsifter and srunner binaries in your $GOPATH/bin.
Add it to your PATH if it isn't already there.
export PATH=$PATH:$GOPATH/bin
To build the linux binary:
GOOS=linux GOARCH=amd64 go install github.com/outten45/cronsifter/cmd/...
Look in the $GOPATH/bin/linux_amd64/ directory for the cronsifter and
srunner.
Here is the general usage of the cronsifter command.
Usage of cronsifter:
-count int
rotate log file count for stdout and stderr files (default 20)
-dir string
directory to write standard out and err log files to (default ".")
-excludes string
the file containing the regular expressions to remove from stdout/stderr
-size int
file size in megabytes to rotate stdout and stderr files (default 20)
The cronsifter command can be run 2 different ways. The command can either call a job command to be run. The other option is to pipe the output of the job command to cronsifter to then filter the results.
Calling the job command from cronsifter
> cronsifter -excludes=excludes.txt command_to_run.sh
Piping the stdout/stderr to cronsifter
> command_to_run.sh | cronsifter -excludes=excludes.txt
A simple program to run the given command and keep it running. It assumes the
command is meant to run in the foreground so if the command stops, srunner
will restart it. srunner will default to waiting 10 seconds before starting
the command again. You can change this by setting the SPAWN_DELAY environment
variable which is parsed using
ParseDuration.
> SPAWN_DELAY="3m" srunner gohttp
This would start the gohttp command and if it failed, srunner would wait 3
minutes before respawning the process.
Thanks to goforever as a reference on how to keep a subprocess running.
