uupick – Command to Process Incoming Files

The uupick command is a utility that is used to process incoming files that have been uploaded to a Unix server using the UUCP (Unix-to-Unix Copy) protocol. It is typically used by system administrators to manage the flow of files between different Unix servers.

Overview

The uupick command is used to retrieve incoming files from a UUCP spool directory and process them according to specified criteria. This command is typically used in conjunction with the uucp command, which is used to send files to remote Unix servers.

The syntax for the uupick command is as follows:

uupick [-b] [-d directory] [-n] [-p pattern] [-r] [-s] [-t timeout]

Here is a brief explanation of each option:

  • -b – This option causes uupick to block until there is at least one file to process.
  • -d directory – This option specifies the directory where incoming files are stored. The default is /usr/spool/uucp.
  • -n – This option causes uupick to not process any files. It is useful for testing purposes.
  • -p pattern – This option specifies a pattern that incoming files must match in order to be processed. The pattern can include shell wildcards.
  • -r – This option causes uupick to remove the processed files from the spool directory.
  • -s – This option causes uupick to process files in strict order of arrival.
  • -t timeout – This option specifies the maximum amount of time that uupick should wait for incoming files before timing out.

Once uupick has processed an incoming file, it can be passed to another command or script for further processing.

Options

Here is a table of all available options for the uupick command:

Option Description
-b Block until there is at least one file to process.
-d directory Specify the directory where incoming files are stored.
-n Do not process any files.
-p pattern Specify a pattern that incoming files must match.
-r Remove processed files from the spool directory.
-s Process files in strict order of arrival.
-t timeout Specify the maximum amount of time to wait for incoming files.

Troubleshooting Tips

If uupick is not processing incoming files as expected, here are a few troubleshooting tips:

  • Check that the UUCP spool directory is set correctly. The default directory is /usr/spool/uucp.
  • Check that the incoming files match the specified pattern, if one was specified.
  • Check that the uucp daemon is running and is configured correctly.
  • Check that the permissions on the spool directory and incoming files are set correctly.

Notes

  • The uupick command is typically used in conjunction with the uucp command, which is used to send files to remote Unix servers.
  • The uupick command is part of the UUCP suite of utilities, which were originally developed for Unix systems but are now available on many other operating systems.
  • uupick can be used in scripts to automate the processing of incoming files.
