Manual page for GETUSERSHELL(3)

getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

char *getusershell()

setusershell()

endusershell()

DESCRIPTION

getusershell() returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells. If /etc/shells does not exist, the four locations of the two standard system shells /bin/sh, /bin/csh, /usr/bin/sh and /usr/bin/csh are returned.

getusershell() reads the next line (opening the file if necessary); setusershell() rewinds the file; endusershell() closes it.

FILES
