PATH
suggest changeThe search path for finding binaries for commands. Common examples include /usr/bin
and /usr/local/bin
.
When a user or script attempts to run a command, the paths in $PATH
are searched in order to find a matching file with execute permission.
The directories in $PATH
are separated by a :
character.
~> $ echo "$PATH"
/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin
So, for example, given the above $PATH
, if you type lss
at the prompt, the shell will look for /usr/kerberos/bin/lss
, then /usr/local/bin/lss
, then /bin/lss
, then /usr/bin/lss
, in this order, before concluding that there is no such command.
