You never said you wanted to store the changes in your original file and your original sed command made no attempt to save the changes.

To do that, you could try:
Code:
sed -n 's/\(^.\{22\}\)..../\10603/
s/\(^.\{29\}\)\( *\)-/\1\2s/
s/\(^.\{29\}\)\( *\)[ +]\([0-9.]\)/\1\2-\3/
s/\(^.\{29\}\)\( *\)s/\1\2 /
p' inputfile > tmp$$ && cp tmp$$ inputfile && rm tmp$$

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

HISTORY

       mkerrlst(1), first appeared in 2.11BSD.

BUGS

       Error messages can be a maximum of 80 characters.
