while read lone
do
...
done < inputfile

Quest for the most useless command

I wrote by accident: cd . and even hit ENTER. Then I realized this is probably the most useless command that you can imagine.

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
