Introducing the File System

6-16

Copying and Renaming Files

The cp command copies an existing ﬁle into a new one. The command cp takes two

arguments, both are either ﬁlenames or pathnames to ﬁles. First, give the name of

the ﬁle you want to copy, followed by the name of the new ﬁle, cp oldﬁle newﬁle.

For example, cp games/bridge hobbies/bridge.

The mv command moves an existing ﬁle into a new one. The command mv takes

two arguments, both are either ﬁlenames or pathnames to ﬁles. First, give the name

of the ﬁle you want to move, followed by the name of the new ﬁle, mv ﬁle1 ﬁle2.

For example, mv games/bridge hobbies/bridge.

The mv and cp commands do not perform the same function. Figure 6-6 displays

the subtle but signiﬁcant difference. The cp command produces a duplicate ﬁle,

maintaining the original ﬁle. The mv command also produces a duplicate ﬁle; how-

ever, it removes the original ﬁle.

If you try to copy or move a ﬁle and get the message “Permission denied,” you may

not have the correct ﬁle access permission to copy or move the ﬁle. Check the ﬁle

access permissions with the ll command. If necessary, try to change the ﬁle access

permissions; refer to chmod(1) in HP-UX Reference Vol. 1 for more information

about understanding and changing ﬁle access permissions. If you cannot change the

ﬁle access permissions yourself, contact your system administrator.
