linux glob cli bash zsh regex



In computer programming, glob patterns specify sets of filenames with wildcard characters. For example, the Unix Bash shell command mv *.txt textfiles/ moves (mv) all files with names ending in .txt from the current directory to the directory textfiles. Here, * is a wildcard standing for “any string of characters” and *.txt is a glob pattern. The other common wildcard is the question mark (?), which stands for one character. In addition to matching filenames, globs are also used widely for matching arbitrary strings (wildcard matching). In this capacity a common interface is fnmatch.
