comparing files - adding/subtracting/formating columns
I have two files:
file1.txt:
FS Total Used Free Used%
/u01 10000 8000 2000 80%
/u02 10000 8000 2000 80%
/u03 10000 8000 2000 80%
/u04 10000 8000 2000 80%
/u05 10000 8000 2000 80%
/u06 10000 8000 2000 80%
/u07 10000 8000 2000 80%
/u10 10000 5000 5000 50%

file2.txt:
FS Adj
/u01 1,500
/u05 500
/u10 2,500

I would like to compare them using the first column in each file and create an output from both that looks like the following:

FS Total Used+Adj Free-Adj (Used+Adj)/Total
--------- -------- --------- --------- ---------
/u01 10,000 9,500 500 95%
/u02 10,000 8,000 2,000 80%
/u03 10,000 8,000 2,000 80%
/u04 10,000 8,000 2,000 80%
/u05 10,000 8,500 1,500 85%
/u06 10,000 8,000 2,000 80%
/u07 10,000 7,500 2,500 75%

Please note that all lines from file1.txt are listed, and column "adj" of file2.txt is added to column "Used" and subtracted from column "Free" of file1.txt only if there is a match.

I was able to produce this report only after loading these files into a database but I am sure I can do it using shell scripting with your help.

Thanks,
Omer

export

asadmin-export(1AS)						   User Commands					       asadmin-export(1AS)

NAME

       asadmin-export, export - marks a variable name for automatic export to the environment of subsequent commands in multimode

SYNOPSIS

       export  [ name=value  [ name=value]*]

       Marks  a variable name for automatic export to the environment of subsequent commands. All subsequent commands use the variable name values
       as specified; unless you unset them or exit multimode. If only the variable name is specified, the current value of that variable  name	is
       displayed.  If  the  export  command  is  used  without	any arguments, a list of all the exported variables and their values is displayed.
       Exported shell environment variables set prior to invoking the asadmin utility are imported automatically and  set  as  exported  variables
       within asadmin. Unexported environment variables cannot be read by the asadmin utility.

OPERANDS

       name=value	       variable name and value for automatic export to the environment to be used by subsequent commands.

       Example 1: Using export to list the environment variables

       asadmin> export AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=password
       asadmin> export AS_ADMIN_PREFIX=server1.jms-service
       asadmin> export //to list the environment variables that are set
       AS_ADMIN_HOST=bluestar
       AS_ADMIN_PORT=8000
       AS_ADMIN_USER=admin
       AS_ADMIN_PASSWORD=********
       AS_ADMIN_PREFIX=server1.jms-service

       Where:  the export command lists the environment variables that are set. In this case, the environment variables have been set to: the host
       is bluestar, the port is 8000, the administrator user is admin with an associated password, and the prefix is server1.jms-service.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command

       asadmin-unset(1AS), asadmin-multimode(1AS)

J2EE 1.4 SDK							    March 2004						       asadmin-export(1AS)
