Need help writing shell script!
Hi, I'm very new to this, so bear with me please.

I want to write a sh script (or if there's a better format please let me know) that allows me to, when I run it, print the date to a file (1.out) take 2 arguments (files a.fa and b.fa), run them with another program, outputting to 2.out, and then printing the date again in 1.out.

So basically something along the lines of:

example.sh
date
./program.exe argv[0] argv[1] >> 2.out #argv[0]_argv[1].out rather than 2.out
date

and I would run example.sh like so:

sh example.sh a.fa b.fa >> 1.out

and 1.out would read:

date1
date2

and 2.out would be the output of the program.

I would also like to name 1.out --> a_b_time.out and 2.out -->a_b.out

Any degree of help would be greatly appreciated.

*edit*

Here's a summary of what I want (to clarify):

So basically I want to run a program and track the start time, the time when the program starts running, to the end time, when the program is finished. What I want the shell script to do is to print the start time to a file, use the arguments entered in the command line as arguments for the program I'm running, and then print the time after the program is done running in the same file that the start time was printed to. I want the file containing the start and end times to be called firstargument_secondargument_time.out and the program output to be called firstargument_secondargument.out.

If there is another method of figuring out how long the program runs for of if you have any more questions, please let me know.

Thanks!

lr_environment

LR_ENVIRONMENT.IN(1)					  LogReport's Lire Documentation				      LR_ENVIRONMENT.IN(1)

NAME

       lr_environment - Export Lire configuration in shell script form

SYNOPSIS

       eval `lr_environment`

DESCRIPTION

       The lr_environment command is used to import the Lire configuration in Lire shell scripts.

       All of Lire configuration variables will be written in a format that can be evaled by the shell.

       Shell scripts don't usually have to use that command, since it is done by the defaults file sourced by each command.

       The old names used by when the configuration was done in shell script are also exported by this script for backward compatibility.
