I want to show only the numbers and characters, not other specific symbols. I tried this:

grep [0-9,A-Z] ika

but working it is not working now, it shows specific symbols also.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

the command you show will display lines with any of those characters in it; what's your desired output? Also, be sure to quote that pattern to protect it from the shell, in case you had a file named , or C in your current directory, you wouldn't get what you expect.

Do you mean numbers and letters? "Symbols" are characters.

The following examples show how to get what you want:

These commands show the whole line containing the search string.

$ <<< 'asdf$@12' grep as

asdf$@12

$ <<< 'asdf$@12' grep '[0-9A-Z]'

asdf$@12

You can high-light the search string in the line

$ <<< 'asdf$@12' grep --color '[0-9A-Z]'

asdf$@12

You can print only the search string (in this case one-character digits and upper case letters)

$ <<< 'asdf$@12' grep --color -o '[0-9A-Z]'

1

2

If you want all letters, you should search for lower case letters too

$ <<< 'asdf$@12' grep --color -o '[0-9A-Za-z]'

Do you want commas displayed in the result? If no, remove from the pattern resp. regex.
