Some shell built-in commands have counterparts that are regular OSS commands of the same
names. The shell built-in version and the OSS version of a command may not behave in the same
way or support the same flags.
The shell built-in version is the default version. To run the OSS version, specify the command as
follows:
/bin/command_name
To make the OSS version the default version, create an alias to it in your .profile file.
The following shell built-in commands also have OSS forms:
•
echo(1)
•
kill(1)
•
pwd(1)
•
read(1)
