I have a file named example
$ cat example kali.pdf linux.pdf ubuntu.pdf example.pdf. this.pdf grep .pdf
and when I use
grep to get the line that has a space before
grep *.pdf example
returns nothing, (I want to say, "grep, match zero or more spaces before
and if I use:
grep i*.pdf example kali.pdf linux.pdf ubuntu.pdf example.pdf. this.pdf grep .pdf
all lines return, because I'm saying "grep, match me
i one or zero times, ok."
grep " *.pdf" example
no result returns
For this sample, I want to see
What is wrong with my thought?
