Linux Commands: source or dot operator


period-Linux Command

period command- source or dot operator

Syntax: "dot" command [period].

. filename [arguments]
 
source filename [arguments]

Description: Equivalent to source. This command, when invoked from the command-line, executes a script. Within a script, a source file-name loads the file file-name. Sourcing a file (dot-command) imports code into the script, appending to the script (same effect as the #include directive in a C program). The net result is the same as if the "sourced" lines of code were physically present in the body of the script. This is useful in situations when multiple scripts use a common data file or function library.
