  1. Glob is the common name for a set of Bash features that match or expand specific types of patterns. Some synonyms for globbing (depending on the context in which it appears) are pattern matching , pattern expansion, filename expansion, and so on
  2. Matching patterns are also called glob patterns. You can use glob patterns for filenames matching but also as part of a Bash If statement where a double bracket condition can perform pattern matching against a string. It is very common to use the Bash Brace Expansion in addition to the Bash Wildcards, though they are two separate Bash features
  3. Extended globbing as described by the bash man page: ?(pattern-list) Matches zero or one occurrence of the given patterns *(pattern-list) Matches zero or more occurrences of the given patterns +(pattern-list) Matches one or more occurrences of the given patterns @(pattern-list) Matches one of the given patterns !(pattern-list) Matches anything except one of the given pattern

A notable exception, bash, provides built-in support for basic globbing. TODO: add list of implementations. Additional readin Bash's built-in extglob option can extend a glob's matching capabilities. The following sub-patterns comprise valid extended globs: The pattern-list is a list of globs separated by |. The pattern-list itself can be another, nested extended glob Bash sees the glob, for example a*. It expands this glob, by looking in the current directory and matching it against all files there. Any filenames that match the glob are gathered up and sorted, and then the list of filenames is used in place of the glob var glob = require ('bash-glob'); glob ('*.js', function (err, files) {if (err) return console. log (err); console. log (files);}); .each Asynchronously glob an array of files that match any of the given patterns

File globbing is a feature provided by the UNIX/Linux shell to represent multiple filenames by using special characters called wildcards with a single file name. A wildcard is essentially a symbol which may be used to substitute for one or more characters. Therefore, we can use wildcards for generating [ With bash one can force the classical behavior using this command: shopt -s nullglob (Similar problems occur elsewhere.

  3. Bash variables are by default global and accessible anywhere in your shell script. Though, in a function, you can limit the scope of a variable by using the local builtin which support all the option from the declare builtin. The syntax for the local keyword is local [option] name[=value]
  4. Wildcards. Wildcards are useful in many ways for a GNU/Linux system and for various other uses. Commands can use wildcards to perform actions on more than one file at a time, or to find part of a phrase in a text file. There are many uses for wildcards, there are two different major ways that wildcards are used, they are globbing patterns/standard wildcards that are often used by the shell

Hi, I wonder if there is anyway to make a user-defined bash shell function global, meaning the function can be use in any bash shell scripts, interactively or not. This is what I attempted: Code The files in the /etc directory generally provide global settings. If an equivalent file exists in your home directory it may override the global settings. An interactive shell is started after a successful , using /bin/ , by reading the /etc/passwd file In the first case, you will get a 0 (the premise is true), and running the second will give you a 1 (the premise is false). Remember that, in Bash, an exit status from a command that is 0 means it exited normally with no errors, and that makes it true. If there were any errors, the exit value would be a non-zero value (false)
