Full Discussion: Run automated bash commands from sh login shell
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

dnssec-signkey

DNSSEC-SIGNKEY(8)														 DNSSEC-SIGNKEY(8)

NAME

       dnssec-signkey - DNSSEC key set signing tool

SYNOPSIS

       dnssec-signkey [ -a ]  [ -c class ]  [ -s start-time ]  [ -e end-time ]	[ -h ]	[ -p ]	[ -r randomdev ]  [ -v level ]	keyset key...

DESCRIPTION

       dnssec-signkey  signs a keyset. Typically the keyset will be for a child zone, and will have been generated by dnssec-makekeyset. The child
       zone's keyset is signed with the zone keys for its parent zone. The output file is of the form signedkey-nnnn.,	where  nnnn  is  the  zone
       name.

OPTIONS

       -a     Verify all generated signatures.

       -c class
	      Specifies the DNS class of the key sets.

       -s start-time
	      Specify  the date and time when the generated SIG records become valid. This can be either an absolute or relative time. An absolute
	      start time is indicated by a number in YYYYMMDDHHMMSS notation; 20000530144500 denotes 14:45:00 UTC on May 30th,	2000.  A  relative
	      start time is indicated by +N, which is N seconds from the current time.	If no start-time is specified, the current time is used.

       -e end-time
	      Specify the date and time when the generated SIG records expire. As with start-time, an absolute time is indicated in YYYYMMDDHHMMSS
	      notation. A time relative to the start time is indicated with +N, which is N seconds from the start time. A  time  realtive  to  the
	      current time is indicated with now+N. If no end-time is specified, 30 days from the start time is used as a default.

       -h     Prints a short summary of the options and arguments to dnssec-signkey.

       -p     Use  pseudo-random data when signing the zone. This is faster, but less secure, than using real random data. This option may be use-
	      ful when signing large zones or when the entropy source is limited.

       -r randomdev
	      Specifies the source of randomness. If the operating system does not provide a /dev/random or equivalent device, the default  source
	      of  randomness  is  keyboard  input.  randomdev  specifies  the name of a character device or file containing random data to be used
	      instead of the default. The special value keyboard indicates that keyboard input should be used.

       -v level
	      Sets the debugging level.

       keyset The file containing the child's keyset.

       key    The keys used to sign the child's keyset.

EXAMPLE

       The DNS administrator for a DNSSEC-aware .com zone would use the following command to sign the  keyset  file  for  example.com  created	by
       dnssec-makekeyset with a key generated by dnssec-keygen:

       dnssec-signkey keyset-example.com. Kcom.+003+51944

       In this example, dnssec-signkey creates the file signedkey-example.com., which contains the example.com keys and the signatures by the .com
       keys.

SEE ALSO

       dnssec-keygen(8), dnssec-makekeyset(8), dnssec-signzone(8).
