Hi. I'm having some problems trying to run the shar program. I have
some files in a directory that I want to put in a shell archive, so I cd to the
directory, then type "shar * > shar.file". This produces a 5-minute wait, and
then a "write failed, disk full" error, as shar keeps writing the same stuff
over and over ad infinitum. Anyone have any help for me?

What apparently happens is that the shell creates the output file before expanding the * into the arguments for shar. Shar goes along and merrily stuff stuff into shar.file; when it gets to shar.file, it starts reading from the beginning and writing to the end. You can avoid this behavior from shar by doing "shar * > somewhere.else/file" - as in put the file somewhere besides the current directory. -- Jay Maynard, EMT-P, K5ZC, PP-ASEL | Never ascribe to malice that which can jmaynard@thesis1.hsch.utexas.edu | adequately be explained by stupidity.

Anyone have any help for me? > The solution is quite simple. When typing shar * > shar.file your shell will also include the file shar.file to the wildcard. This because the file shar.file is created before the wildcard is fully expanded. Therefore it will put this output file again in the output file etc. This causes the disk full message. So make sure the output file is not in the wildcard e.g. by putting the output file in another directory. Marten -- " Quidquid Latine Dictum Sit, Altum Viditur.
