8.1.3 File path names
Files can be specified using absolute path names or relative path names.
Some commands require relative path names to be converted to absolute path names, which means that the length of the path name for a file specified in a command must sometimes be evaluated in terms of the equivalent absolute path name.
The following examples illustrate use of the absolute path name for a file specified in a command.
- Organization of this subsection
(1) When the file name specification is an absolute path name
The file name is specified using the absolute path name.
- Example
/dir1/test1.asc
(2) When the file name specification is a relative path name
The absolute path name is the concatenation of the current directory at the time the command is executed with the path name of the specified file.
- Example
Current directory when command is executed: /home/user1 Path name of file: dir2/test2.asc Absolute path name of file: /home/user1/dir2/test2.asc
