(8) Filename Wildcards

Filename Wildcards

Allows entry of file names with less typing
Pattern Matching Operators
* - Match zero or more characters.
? - Match a single character
[...] - Match a range of characters
Ex. ls exam[12345] will match files exam1-exam5; can specify a range with ls exam[1-5]
[^..] - Match any character NOT named (tcsh)
^pattern - Match file names NOT matching the pattern
ls exam* - Lists all files that begin with the string "exam"
Dot files do not match unless an explicit (.) starts the pattern, treated as special files. Otherwise, a "." elsewhere in the filename is not special.
Pattern operators can be combined
To check patterns before executing
echo pattern
Wildcards are not full regular expressions. Sed, grep, awk etc. work with more flexible (and more complex) string matching operators.
