One might be dealing with commands that can only accept one or maybe two arguments at a time. For example, the diff command operates on two files at a time. The -n option to xargs specifies how many arguments at a time to supply to the given command. The command will be invoked repeatedly until all input is exhausted.
A copy outside revision control is known as a "working copy". As a simple example, when editing a computer file, the data stored in memory by the editing program is the working copy, which is committed by saving. Concretely, one may print out a document, edit it by hand, and only later manually input the changes into a computer and save it.
Variable files: files whose content is expected to continually change during normal operation of the system, such as logs, spool files, and temporary e-mail files. /var/cache: Application cache data. Such data are locally generated as a result of time-consuming I/O or calculation. The application must be able to regenerate or restore the data.
Spaces and symbols such as a "/" or a "-" may be used to allow the command processor to parse the command line into filenames, file specifications, and other options. The command interpreter preserves the case of whatever parameters are passed to commands, but the command names themselves and file names are case-insensitive.
A well-known example of this is the ping utility. [7] ICMP responses will be allowed back through the firewall. In some scenarios, UDP communication can use ICMP to provide information about the state of the session so ICMP responses related to a UDP session will also be allowed back through.
VFAT, a variant of FAT with an extended directory format, was introduced in Windows 95 and Windows NT 3.5. It allowed mixed-case Unicode long filenames (LFNs) in addition to classic 8.3 names by using multiple 32-byte directory entry records for long filenames (in such a way that old 8.3 system software will only recognize one as the valid directory entry).
