Monitor a folder for new/change files

I would like to know how to automate an already made shell script (all the steps of all the commands done on a specific folder) by utilizing a list (a .txt) of all folder names that the shell scripts goes and executes

For example:

In the working folder called main/ there are subfolders named folder1, folder2, folder3.....folder100 and shell script shell.sh.

vi shell.sh

Code: perl au

I am currently in Afghanistan and do not have access to some of the resources I normally do back in the US. Just accessed this site and it looks promising! Hopefully you will not find my question too much of a waste of your time. I write mostly Korn Shell and PERL on Solaris systems for the Army.

I am new to shell script. I have two perl scripts for text processing based on two different input files.I would like to have one shell script that run based on conditions.

if(input file) matches word /extraction_reversed/ run perlscript1.pl otherwise run perlscript2.pl.

Shell script to compile in terminal

sh run.sh inputfile > outputfile

Hi Folks,

I have a script that I am using.

Hello Smart People!

I have a perl script that will import xml data into an access db.

I would like to modify it so it will automatcially parse through all xml files in the folder. I swa a post but couldnt get it working.

In the Perl documentation, perlrun(1) suggests launching Perl scripts using a bilingual shell/Perl header:

#!/bin/sh #! -*-perl-*- eval 'exec perl -x -wS $0 ${1+"$@"}' if 0;

What does ${1+"$@"} mean? I tried using "$@" instead (using Bash as /bin/sh), and it seems to work just as well.

Edit

Two answers below say that it's supposed to be ${1:+"$@"}.

I have a folder in my server which contains some files. These are automated that means everyday we get new files automatically which will overwrite the old ones. So want to take a back up for this data. How can i copy all these files in to a another folder by renaming the files with current date while copying.

ex : i have a folder named folder1 which contains 4 files.
