Hi All,
I have found some idea to handle this situation.
Actually, each lines contains only 80 characters. But as per specification document, 540 characters are of HEADER and then 540 characters are of DETAIL RECORD and very last row is FOOTER record.
In this case, 6 lines (of 80 characters) and 7th lines (with 60 characters) is a HEADER RECORD.
Starting from 61th caracter of 7th lines till 40th character of 14th lines will be DETAIL RECORD 1 and so on...
Is it possible to read line by line and count the characters and seperate the record?
Can somebody help me to write this type of logic or any other idea?

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a filename containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
