Full Discussion: HISTSIZE environment variable problem

I have deleted the duplicate thread.

HISTSIZE controls the size of the history list. HISTFILE controls where the history is stored. But they must be set when ksh first does something with the history list. Setting them later has no effect. Exporting them into the environment ensures that they will affect shells spawned later. But that won't stop the rule that each ksh process looks at them once and once during its lifetime. I don't know what "the HISTSIZE is set to 20 already" is supposed to mean. If you set that in the environment prior to invoking ksh, it should work. But most likely you are setting the variable in a startup file (thus after ksh starts to run) and you are setting too it late. Note that ksh writes functions into the history (unless nolog is on). Did you define a function prior to setting HISTSIZE?

env

ENV(1)							    BSD General Commands Manual 						    ENV(1)

NAME

     env -- set and print environment

SYNOPSIS

     env [-i] [name=value ...] [utility [argument ...]]

DESCRIPTION

     env executes utility after modifying the environment as specified on the command line.  The option name=value specifies an environmental
     variable, name, with a value of value.  The option '-i' causes env to completely ignore the environment it inherits.

     If no utility is specified, env prints out the names and values of the variables in the environment, with one name=value pair per line.

EXIT STATUS

     env exits with one of the following values:

     0	     utility was invoked and completed successfully.  In this case the exit code is returned by the utility itself, not env.  If no util-
	     ity was specified, then env completed successfully and returned the exit code itself.

     1	     An invalid command line option was passed to env.

     1-125   utility was invoked, but failed in some way; see its manual page for more information.  In this case the exit code is returned by the
	     utility itself, not env.

     126     utility was found, but could not be invoked.

     127     utility could not be found.

COMPATIBILITY

     The historic - option has been deprecated but is still supported in this implementation.

SEE ALSO

     execvp(3), environ(7)

STANDARDS

     The env utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').

BUGS

     env doesn't handle commands with equal (``='') signs in their names, for obvious reasons.
