So the file has no line feed, you just want to get rid of the last byte. If you have gnu "head" you can do
Or you can use dd to truncate the file in place (make backup if you need):
Of course dd can do "head -c" too:
If your input had line feed, you could truncate to size-2 and then append a line feed to it.

mkerrlst
MKERRLST(1) General Commands Manual MKERRLST(1)NAME
mkerrlst - create system error file
SYNOPSIS
mkerrlst [ -i inputfile ] [ -o outputfile ]
DESCRIPTION Mkerrlst(1) creates error message files in the format described by syserrlst(5).
With no arguments mkerrlst creates the file /etc/syserrlst from the internal array sys_errlist.
Give just the -o option mkerrlst will create the file outputfile from the internal array sys_errlist.
Given just the -i option mkerrlst will create the file /etc/syserrlst from the input file inputfile.
Given both -i and -o options mkerrlst will create the error message file outputfile from the strings contained in inputfile.
NOTE: error messages are numbered from 0. If the error 0 does not have a message associated with it the first string in inputfile must
still be present.
RETURN VALUE
mkerrlst exits with status of 0 if no errors are encountered. If errors do occur an error message is printed on stderr and the exit status
is 1.
ERRORS mkerrlst(1) can encounter any of the errors for the open(2), lseek(2), read(2), or write(2) system calls.
SEE ALSO syserrlst(3)syserrlst(5)HISTORY mkerrlst(1), first appeared in 2.11BSD.
