Rename Multiple Files in Bash Using Regular Expressions - Bash. Cp MAN Page. Copy one or more files to another location Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY. Syntax cp [options]... Source Dest cp [options]... Source... By default, sparse SOURCE files are detected by a crude heuristic and the corresponding DEST file is made sparse as well. That is the behavior selected by --sparse=auto.
Specify --sparse=always to create a sparse DEST file whenever the SOURCE file contains a long enough sequence of zero bytes. Use --sparse=never to inhibit creation of sparse files. The backup suffix is ~, unless set with SIMPLE_BACKUP_SUFFIX. The version control may be set with VERSION_CONTROL, values are: t, numbered make numbered backups nil, existing numbered if numbered backups exist, simple otherwise never, simple always make simple backups As a special case, cp makes a backup of SOURCE when the force and backup options are given and SOURCE and DEST are the same name for an existing, regular file.
Examples Copy demofile to demofile.bak : $ cp -f /mnt/floppy/* ~ BASH Basics.

General At times you need to specify different courses of action to be taken in a shell script, depending on the success or failure of a command. The if construction allows you to specify such conditions.
The most compact syntax of the if command is: if TEST-COMMANDS; then CONSEQUENT-COMMANDS; fi The TEST-COMMAND list is executed, and if its return status is zero, the CONSEQUENT-COMMANDS list is executed. The TEST-COMMAND often involves numerical or string comparison tests, but it can also be any command that returns a status of zero when it succeeds and some other status when it fails. 7.1.1.1. The table below contains an overview of the so-called "primaries" that make up the TEST-COMMAND command or list of commands.
