HOW: Shell script accessing files located in individual logged in user.
Hi
I have below scenario, I hope this could be possible, but as of now no idea how to implement this.
Mount point in this location /abc/mp, and there will different users who will be executing one the file shell1.sh file located in /abs/mp, but every user will execute this shell1.sh file from their login
(somtehing like this /aaa/bbb/home/usr1)
I am sure that above step can be implemented by creating link in /abc/mp for each individual users
Now real question is
In my shell1.sh file which is in /abc/mp, have to pick one of the file dynamically (I mean not hardcoded path/file) from certain folder for logged in user
i.e. for example
- File in /abc/mp is shell1.sh
- Individual logged in user is usr1
So usr1 will execute this shell1.sh file using link
The shell1.sh should be able to pick the file namely mydatafile.txt from individual logged in user from certain folder in /aaa/bbb/home/usr1/dump
(Similarly if usr2 executes this shell1.sh then shell file should able to pick mydatafile.txt located in usr2's location that is /aaa/bbb/home/usr2/dump )
I just like to know how this can be implemented, might be very simple but I am not aware of this.
Regards
jc

adsl-connect
ADSL-CONNECT(8) System Manager's Manual ADSL-CONNECT(8)
NAME
adsl-connect - Shell script to manage a PPPoE link
SYNOPSIS
adsl-connect [config_file]
adsl-connect interface user [config_file]
DESCRIPTION
adsl-connect is a shell script which manages an ADSL connection using the Roaring Penguin user-space PPPoE client. If you omit con-
fig_file, the default file /etc/sysconfig/network-scripts/ifcfg-ppp0 is used. If you supply interface and user, then they override the
Ethernet interface and user-name settings in the configuration file.
Note that normally, you should not invoke adsl-connect directly. Instead, use adsl-start to bring up the ADSL connection.
adsl-connect first reads a configuration file. It then brings up a PPPoE connection. If the connection ever drops, a message is logged to
syslog, and adsl-connect re-establishes the connection. In addition, each time the connection is dropped or cannot be established, adsl-
connect executes the script /etc/ppp/adsl-lost if it exists and is executable.
The shell script adsl-stop causes adsl-connect to break out of its loop, bring the connection down, and exit.
TECHNICAL DETAILS
adsl-connect uses the following shell variables from the configuration file:
ETH The Ethernet interface connected to the ADSL modem (for example, eth0).
USER The ADSL user-id (for example, b1xxnxnx@sympatico.ca).
PIDFILE
A file in which to write the process-ID of the adsl-connect process (for example, /var/run/pppoe.pid). Two additional files ($PID-
FILE.pppd and $PIDFILE.pppoe) hold the process-ID's of the pppd and pppoe processes, respectively.
By using different configuration files with different PIDFILE settings, you can manage multiple PPPoE connections. Just specify the con-
figuration file as an argument to adsl-start and adsl-stop.
