Operating Systems Solaris Run automated bash commands from sh login shell Post 303015972 by randman1 on Tuesday 17th of April 2018 12:15:48 PM

The remote servers have thousands of CSV files organized into 3 groups. The user supplies a start and end date and the script returns the records between the supplied dates/times. The script must first determine which files should contain the correct data (determined by file name = $filelist) then determine which lines from those files are between the start and end date (determined by unix timestamp field). The perl functions are to convert the user-supplied start and end date/time to epoch timestamp so time is relative to the server, not the user. This enabled me to skip time zone and DST implementation in the GUI since users can be in different time zones.

I did run the commands from an interactive session, which is a convenient way to test since it mimics what plink is doing. This is where I was seeing the undefined variable messages. When i included a pwd command, I found that the cd command was not executed either.

Since the initial post though, I learned that quoting the heredoc delimiter works. All the commands appeared to have run in bash and provided an output.
Code:
/bin/bash << "eof"
...
"eof"

I'm still not sure why this works but glad it does. I'm still faced with the timestamp conversion issue though. I played around with similar perl commands inside the nawk statement but am not having much luck. This issue doesn't have as big of an impact as did running the commands in bash instead of sh but it would be nice to resolve it.

Edit: I just realized that the login shell for these Solaris 10 boxes is csh rather than sh. Not sure is that changes things much

uuxqt(1)						      General Commands Manual							  uuxqt(1)

NAME
uuxqt - Executes remote command requests SYNOPSIS
uuxqt [-ssystem] [-xdebug_level] The uuxqt program executes specified commands on designated remote systems. OPTIONS
Specifies the name of the remote system. Use this option only when starting uuxqt manually. The remote system name is supplied internally when uuxqt is started automatically. Displays debugging information on the screen of the local system; debug_level is a single digit between 0 and 9. The higher the number specified, the more detailed the debugging information displayed. DESCRIPTION
When uux is entered by a user, the program creates the necessary C.* (Command), D.* (Data), and X.* (Execute) files and places them in the spooling directory on the designated remote system. The uux command then calls the uucico daemon which in turn, tries to contact the designated system to deliver the files. When the files are transferred, uuxqt executes the commands on the designated system. The uuxqt program searches the spool directories on the designated system for the X.* (Execute) files whose names indicate that they were sent from another system. The command checks each X.* file for the following: All of the required D.* (Data) files must be available and accessible. File commands must be permitted for the requesting system. The uuxqt program can be executed manually by a user with superuser privileges. This daemon is executed automatically by the uudemon.hour shell script, which is started periodically by cron. FILES
Lock file which prevents multiple use of device Limits number of remote command executions Access permission codes SEE ALSO
Commands: uucico(8), uucp(1), uustat(1), uux(1) uuxqt(1)
