ls-F built-in command for tcsh: List files

Format

ls-F [-switch …] [file …]

Description

In the tcsh shell, ls-F lists files like ls -F, but works much faster. It identifies each type of special file in the listing with a special character:

/: Directory
*: Executable
#: Block device
%: Character device
|: Named pipe
=: Socket
@: Symbolic link

If the listlinks shell variable is set, symbolic links are identified in more detail on systems that have them.

@: Symbolic link to a non-directory
>: Symbolic link to a directory
&: Symbolic link to nowhere

listlinks also slows down ls-F.

If you use files that are set up as follows:

#creating a file
   touch file1
#creating a symbolic link to the file
   ln -s file1 link1
#creating a directory
   mkdir dir1
#creating a symbolic link to the directory
   ln -s dir1 linkdir1
#creating a symbolic link to a file that doesn't exist
   ln -s noexist linktonowhere

when you issue an ls-F with listlinks unset, you will get the following output:

> ls-F
dir1/ file1 link1@ linkdir1@ linktonowhere@
>

with listlinks set:

> set listlinks>
 ls-F
dir1/ file1 link1@ linkdir1> linktonowhere&
>

If the listflags shell variable is set to x, a or A, or any combination thereof (for example, xA), they are used as flags to ls-F, making it act like ls -xF, ls -Fa, ls -FA or a combination ls -FxA. On z/OS systems, ls -C is the default. However, on machines where ls -C is not the default, ls-F acts like ls -CF, unless listflags contains an x, in which case it acts like ls -xF.

See tcsh — Invoke a C shell.
