need assistance ----SH schell script
Hello All,
I need to develop a script(SH]) to generate a comparison file between two files old and new file.The script takes in parameter the old file path and the new file path. And the script generates a file containing the comparison between the two files with this details:
- Keys added on the new file (key=value)
- Keys modified on the new file (key=value)
- Keys deleted on the new file (key=value)
key column is the 4th one and value column is the 6th one in the sample file.
Example:
old file: key1,value1 new file:key4,value3
key4,value4 key6,value6
output file: comparison file
------------------
1> keys added ----- key6,value6
2>deleted ---------- key1,value1
3> modified---------- key4,value3
I'm new to schell scripting field. request you to explain briefly along with the code. any sort of assistance would be appreciated.
Thanks in advance
Regards Shahid.

script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
