Remove new line character and add space to convert into fixed width file

I have a file with different record length. The file as to be converted into fixed length by appending spaces at the end of record. The length should be calculated based on the record with maximum length in the file.

If the length is less than the max length, the spaces should be appended before the new line character of that record.

Code:
 
Input File:
123
12345
1234
 
Output file:
123  
12345
1234 
 
Here the max record length is 5

NAME
audit - write a record to the audit log SYNOPSIS
cc [ flag ... ] file ... -lbsm -lsocket -lnsl [ library... ] #include <sys/param.h> #include <bsm/libbsm.h> int audit(caddr_t record, int length); The audit() function is used to write a record to the system audit log. The data pointed to by record is written to the log after a mini- mal consistency check, with the length parameter specifying the size of the record in bytes. The data should be a well-formed audit record as described by audit.log(4). The kernel validates the record header token type and length, and sets the time stamp value before writing the record to the audit log. The kernel does not do any preselection for user-level generated events. If the audit policy is set to include sequence or trailer tokens, the kernel will append them to the record. Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error. The audit() function will fail if: EFAULT The record argument points outside the process's allocated address space. EINVAL The record header token ID is invalid or the length is either less than the header token size or greater than MAXAUDIT- DATA. EPERM The {PRIV_PROC_AUDIT} privilege is not asserted in the effective set of the calling process. USAGE
Only privileged processes can successfully execute this call.
