CPIO(1)
NAME
cpio - copy file archives in and out
SYNOPSIS
cpio -o [ #aBchv ] [ name-list ]
cpio -i [ #BcdhmrtuvfsSb6 ] [ patterns ]
cpio -p [ adlmruv ] directory
DESCRIPTION
Cpio -o (copy out) uses the name-list arguments, or reads the standard input
to obtain a list of path names and copies those files onto the standard output
(or to the device /dev/rmt#) together with path name and status informa-
tion.
Cpio -i (copy in) extracts files from the standard input (or from the device
/dev/rmt#) which is assumed to be the product of a previous cpio -o.
Only files with names that match patterns are selected. Patterns are given in
the name-generating notation of sh(1). In patterns, meta-characters ?, *, and
[...] match the slash / character. Multiple patterns may be specified and if
no patterns are specified, the default for patterns is * (i.e., select all files).
The extracted files are conditionally created and copied into the current
directory tree based upon the options described below.
Cpio -p (pass) reads the standard input to obtain a list of path names of files
that are conditionally created and copied into the destination directory tree
based upon the options described below.
The meanings of the available options are:
# Use /dev/rmt# as input (for -i) or output (for -o). Note: 6 has another
meaning described below.
a Reset access times of input files after they have been copied.
B Input/output is to be blocked 5,120 bytes to the record (does not apply
to the pass option; meaningful only with data directed to or from /dev/
rmt?).
c Write header information in ASCII character form for portability.
d Directories are to be created as needed.
h Similar to B option, but block input/output to 250K bytes. This option is
only useful for streaming tape drive operation.
r Interactively rename files. If the user types a null line, the file is skipped.
t
Print a table of contents of the input. No files are created.
u
Copy unconditionally (normally, an older file will not replace a newer file
with the same name).
v Verbose: causes a list of file names to be printed. When used with the t
option, the table of contents looks like the output of an ls -l command
(see ls(1)).
l Whenever possible, link files rather than copying them. Usable only with
the -p option.
m
Retain previous file modification time. This option is ineffective on
directories that are being copied.
f Copy in all files except those in pattems.
s Swap bytes. Use only with the -i option.
S Swap halfwords. Use only with the -i option.
