It also provides a version of find. dir has the /s option that recursively searches for files or directories. Plan 9 from Bell Labs uses two utilities to replace find: a walk that only walks the tree and prints the names and a sor that only filters (like grep) by evaluating expressions in the form of a shell script. Arbitrary filters can be ...
In computing, tree is a recursive directory listing command or program that produces a depth-indented listing of files. Originating in PC- and MS-DOS , it is found in Digital Research FlexOS , [ 1 ] IBM / Toshiba 4690 OS , [ 2 ] PTS-DOS , [ 3 ] FreeDOS , [ 4 ] IBM OS/2 , [ 5 ] Microsoft Windows , [ 6 ] and ReactOS .
In computing, the utility diff is a data comparison tool that computes and displays the differences between the contents of files. Unlike edit distance notions used for other purposes, diff is line-oriented rather than character-oriented, but it is like Levenshtein distance in that it tries to determine the smallest set of deletions and insertions to create one file from the other.
A screenshot of the original 1971 Unix reference page for glob – the owner is dmr, short for Dennis Ritchie.. glob() (/ ɡ l ɒ b /) is a libc function for globbing, which is the archetypal use of pattern matching against the names in a filesystem directory such that a name pattern is expanded into a list of names matching that pattern.
inotify (inode notify) is a Linux kernel subsystem created by John McCutchan, which monitors changes to the filesystem, and reports those changes to applications.It can be used to automatically update directory views, reload configuration files, log changes, backup, synchronize, and upload.
Copy a file to a new file and preserve the modification date, time, and access control list associated with the source file: cp -p smith smith.jr This copies the smith file to the smith.jr file. Instead of creating the file with the current date and time stamp, the system gives the smith.jr file the same date and time as the smith file.
Renames files and folders simultaneously. Recursive selection - loads files in directory and in subdirectories. Undo an operation. Wide use of regular expressions: when selecting items, for search/replace, etc.. Reading of metadata such as ID3 and Exif tags, or creation/modification/last access time. Change length of names. Change case in ...
Windows based on the NT kernel (XP, Vista, 7, 8, Server 2003/2008) are case insensitive, just like their earlier predecessors, unless two files of the same name and different case exist. Then case sensitivity applies when selecting which file to use, or if the case does not match either file, one may be chosen by Windows.
