Step 1)

When writing scripts, you do not include the "$" at the beginning of the line, since in a shell, the "$" is actually the command prompt. The $ has a specific meaning within the shell program itself (it is used to reference variables).


Thus, in the example you supplied, vi a file called "myscript.sh". The script program would look similar to the following:

Code:
#!/bin/sh
echo "Today's date is `date`"

Note the quotes around the echo statement. This is due to the fact that you have an apostrophe within the desired phrase.

Step 2) Save the file and chmod +x myscript.sh
Step 3) ./myscript.sh

Code:
$ vi myscript.sh
$ chmod +x myscript.sh
$ ./myscript.sh



or

Step 3a) echo $PATH to see if the directory where "myscript.sh" is included, if not, include it using the following (for a Bourne/Korn shell or equivalent) into your login profile

PATH=$PATH:/newdirectorytoadd
export PATH

for csh users,

set path=($path /newdirectorytoadd)

or

setenv PATH ${PATH}:/newdirectorytoadd

(I'm not a csh power user, so double check this...)

Step 3b) at the command prompt, just execute the myscript.sh file


Code:
$ vi myscript.sh
$ chmod +x myscript.sh
$ PATH=$PATH:/this/is/the/directory
$ export PATH
$ myscript.sh


Don't think I can get much more explicit, I hope this helps.

nqs2pbs

nqs2pbs(1B)								PBS							       nqs2pbs(1B)

NAME

       nqs2pbs - convert NQS job scripts to PBS

SYNOPSIS

       nqs2pbs nqs_script [pbs_script]

DESCRIPTION

       This  utility  converts	a  existing NQS job script to work with PBS and NQS.  The existing script is copied and PBS directives, #PBS , are
       inserted prior to each NQS directive #QSUB or #@$ , in the original script.

       Certain NQS date specification and options are not supported by PBS.  A warning message will be displayed indicating the  problem  and  the
       line of the script on which it occurred.

       If  any	unrecognizable	NQS  directives  are encountered, an error message is displayed.  The new PBS script will be deleted if any errors
       occur.

OPERANDS

       nqs_script
	      Specifies the file name of the NQS script to convert.  This file is not changed.

       pbs_script
	      If specified, it is the name of the new PBS script.   If not specified, the new file name is nqs_script.new .

NOTES

       Converting NQS date specifications to the PBS form may result in a warning message and an incompleted converted date.  PBS does not support
       date  specifications  of  "today",  "tomorrow", or the name of the days of the week such as "Monday".  If any of these are encountered in a
       script, the PBS specification will contain only the time portion of the NQS specification, i.e. #PBS -a hhmm[.ss].   It is  suggested  that
       you specify the execution time on the qsub command line rather than in the script.

       Note that PBS will interpret a time specification without a date in the following way:

       -  If the time specified has not yet been reached, the job will become eligible to run at that time today.

       -  If the specified time has already passed when the job is submitted, the job will become eligible to run at that time tomorrow.

       PBS does not support time zone identifiers.  All times are taken as local time.
