1. UNIX/Linux
Devise wild-card patterns to match the following filenames: (i) foo1, foo2, and Foo5, (ii) quit.c,
quit.o, and quit.h, (iii) watch.htm, watch.HTML, and Watch.html, (iv) all filenames that begin
with a dot and end with .swp.
Solution
i) foo1, foo2, and Foo5
[f,F]oo[1,2,5]
[f,F] means first character could be f or F then oo then last could be 1 2 5
ii) quit.c, quit.o, and quit.h,
quit.?
?:any single charater after quit
iii) watch.htm, watch.HTML, and Watch.html
-i watch.htm[?, ]
-i ignore case
? any single character character ot empty
4.all filenames that begin with a dot and end with .swp.
^.swp$
^ denotes begining
$ denotes endingof line
