So if I wanted to replace the occurrences recursively, is that impossible? Was wrong in thinking find and sed could do this?

ausyscall
AUSYSCALL:(8) System Administration Utilities AUSYSCALL:(8)
NAME
ausyscall - a program that allows mapping syscall names and numbers
SYNOPSIS
ausyscall [arch] name | number | --dump | --exact
DESCRIPTION
ausyscall is a program that prints out the mapping from syscall name to number and reverse for the given arch. The arch can be anything
returned by `uname -m`. If arch is not given, the program will take a guess based on the running image. You may give the syscall name or
number and it will find the opposite. You can also dump the whole table with the --dump option. By default a syscall name lookup will be a
substring match meaning that it will try to match all occurrences of the given name with syscalls. So giving a name of chown will match
both fchown and chown as any other syscall with chown in its name. If this behavior is not desired, pass the --exact flag and it will do an
exact string match.
This program can be used to verify syscall numbers on a biarch platform for rule optimization. For example, suppose you had an auditctl
rule:
-a always, exit -S open -F exit=-EPERM -k fail-open
If you wanted to verify that both 32 and 64 bit programs would be audited, run "ausyscall i386 open" and then "ausyscall x86_64 open". Look
at the returned numbers. If they are different, you will have to write two auditctl rules to get complete coverage.
-a always,exit -F arch=b32 -S open -F exit=-EPERM -k fail-open
-a always,exit -F arch=b64 -S open -F exit=-EPERM -k fail-open
For more information about a specific syscall, use the man program and pass the number 2 as an argument to make sure that you get the
syscall information rather than a shell script program or glibc function call of the same name. For example, if you wanted to learn about
the open syscall, type: man 2 open.
OPTIONS
--dump Print all syscalls for the given arch
--exact
Instead of doing a partial word match, match the given syscall name exactly.
