ex: Open a file.
$ ex ${filename}
try on your machine
The command "ex ${filename}" is composed of two parts.
-
"ex" is the name of a UNIX text editor that allows users to create and modify text files.
-
"${filename}" is a placeholder representing the variable "filename". The "${filename}" syntax is commonly used in UNIX systems to define and refer to variables.
Therefore, "ex ${filename}" is a command that instructs the ex editor to open and edit the file with the name specified in the variable "filename". The specific actions that can be performed with the "ex" editor depend on the chosen editing mode and the commands used within it.
