16.3 Looking Around With ls 231

Figure 16.8: Adding an alias for the ls command to the .bashrc ﬁle

Simply pressing Enter will save your changes to your .bashrc ﬁle.

You won’t be able to see your changes take effect until you close your xterm window and open a new

xterm. Once you do that, you’ll see your modiﬁcations take effect.

Here’s a short list of some popular options with ls. Remember, you can view the full list by reading

the ls man page (man ls).

-a – all. Lists all the ﬁles in the directory, including the hidden ﬁles (.filename). The .. and .

at the top of your list refer to the parent directory and the current directory, respectively.

-l – long. Lists details about contents, including permissions (modes), owner, group, size,

creation date, whether the ﬁle is linked to somewhere else on the system and where its link

points.

-F –ﬁle type. Adds a symbol to the end of each listing. These symbols include / to indicate a

directory; @ to indicate a symbolic link to another ﬁle; * to indicate an executable ﬁle.

-r – reverse. Lists the contents of the directory from back to front.

-R – recursive. This recursive option lists the contents of all directories (below the current

directory) recursively.

-S – size. Sorts ﬁles by their size.
