- <h4 align=center>OS/161 Reference Manual</h4>
- <h3>Name</h3>
- ls - list files or directory contents
- <h3>Synopsis</h3>
- /bin/ls [-adlRs] [<em>path</em>...]
- <h3>Description</h3>
- ls lists the filesystem objects specified on the command line. If they
- are directories, the contents of the directories are listed (unless
- the -d option is used).
- <p>
- If the -a option is given, filenames beginning with dot (.) will be
- listed. Ordinarily, they are skipped.
- <p>
- If the -d option is given, directory contents will not be listed; the
- directories themselves will be.
- <p>
- If the -l option is given, a long format listing showing the file
- size, type, and link count will be displayed instead of just the
- filenames.
- <p>
- If the -R option is given, subdirectories encountered will be listed
- recursively.
- <p>
- If the -s option is given, the number of filesystem blocks used by
- each object will be displayed in addition to other information.
- <p>
- If no <em>paths</em> are specified, the current directory is assumed.
- <h3>Requirements</h3>
- ls uses the following syscalls:
- <ul>
- <li> <A HREF=../syscall/open.html>open</A>
- <li> <A HREF=../syscall/write.html>write</A>
- <li> <A HREF=../syscall/fstat.html>fstat</A>
- <li> <A HREF=../syscall/getdirentry.html>getdirentry</A>
- <li> <A HREF=../syscall/close.html>close</A>
- <li> <A HREF=../syscall/_exit.html>_exit</A>
- </ul>
- ls should function properly once the file system assignment is
- completed.
