Repeat - a command line utility

This command line program will execute a command repeatedly. It is intended to replace the shell pattern:

while something; do sleep $seconds; done

With options, it is considerably more flexible.

Options

• --interval duration - Specifies an interval between invocations. Defaults to 0.
• --times num - Executes for a maximum number of times, then exit.
• --untilerr - Stops repeating when the command's exit code is non-zero
• --untilsuccess - Stops repeating when the command's exit code is zero
• --precise - Runs command at specified intervals instead of waiting the interval between executions.
• --noshell - Runs command directly instead of via an intermediate shell
• --help - Display usage and exit
• --version - Display version info and exit

Examples

• repeat echo Hello World Prints out Hello World forever
• repeat -n 5 echo Hello World Prints out Hello World five times
• repeat -i 1 echo Hello World Prints out Hello World with a second between each invocation
• repeat -i 1 -e -p -t 5 echo Hello World Prints out Hello World five times, once a second, stopping if echo returns an error.
• repeat -i 5 -s grep foobar myfile Checks every seconds for foobar in myfile until it succeeds.
