V6scripts

The V6scripts project contains a collection of shell scripts, aka command files, provides some working examples of osh and sh6 scripting.

The INSTALL script in the collection automatically converts all of the sh6 command files to run with osh if sh6, glob6, if, goto, and fd2 are not installed on a given system.

Osh command files

The following command files run with osh(1):

 * alarm.osh - Sleepy? Use the shell and terminal as an alarm clock.

 * circalc.osh - Calculate 3 values representing the size of a circle.
 * dirname.osh - Print the directory portion of a pathname.
 * intcmp.osh - Compare 2 integers according to the given operator.

 * ll.osh - Alias `ll ...' to `ls -AlF [options] [file ...]'.
 * mksums.osh - Print a list of checksums for the given file(s).
 * ncat.osh - Concatenate/print files w/ line numbers.

Sh6 command files

The following command files run with sh6(1):

 * counts.sh6 - Demonstrate using `shift' to control loop iteration.
 * finfo.sh6 - Print information about a file or directory.
