Invocation
If the shell is invoked by exec, and the first character of argument zero ($0)is- (dash), the shell
is assumed to be a login shell and commands are read from /etc/profile and then from either
.profile in the current directory or $HOME/.profile, if either file exists. Next, commands are
read from the file named by performing parameter substitution on the value of the ENV environ-
ment variable, if the file exists. If the -s flag is not present and argument is present, a path search
is performed on the first argument to determine the name of the script to execute. The script
argument must have read permission and any setuid and getgid settings are ignored. Commands
are then read, as described in the following text.
See the FLAGS section for a complete description of flags that can be interpreted by the shell
when it is invoked.
FILES
/etc/profile System profile.
$HOME/.profile User profile.
NOTES
1. If a command is executed, and a command with the same name is installed in a directory
in the search path before the directory where the original command was found, the shell
will execute the original command. Use the hash command to correct this situation.
