Using the capital -R may be the nicer habit to get into for As a couple of quick side notes, the rm command also supports both -R and -r to do the same thing, but the In the case ofĭebian, and likely many others, -R also remains an So, for example, the following may work:ĭebian's cp) may support -r.

So those who are used to MS-DOS and That gets copied, this ends up completely destroying the contents of theįinal file. Instead of having the last file be one of the source files This incorrect usage causesĭata loss because the last file ends up being theĭestination file.

This is an importantĭifference from MS-DOS and similar copying systems.
Note that the final parameter must be a destination. (Users familiar with other operating systems should read the Techniques described in the section aboutĪsterisks.
