Grep 特殊字符#'

Question

trying to grep "#'om" but not able to escape or account for the quote char. I tried grep -F , grep -e , grep -n or simply grep "#\'om" to no avail.

Answer 1

That quote is not the simple quote character it appears to be. It's not clear whether copying-and-pasting the quote character from this website is accurate.

$ echo '‘' | cat -v
M-bM-^@M-^X

$ echo '‘' | xxd
$ 00000000: e280 980a                                ....

So, it appears the problem is one of character sets.

Note, however, that the following works for me:

$ echo '‘' | grep -F '‘'
‘

As does the following:

$ echo '#‘om' | grep -F '#‘om'
#‘om

It would help to see exactly what is being tried. Perhaps use xxd to confirm what bytes are making up that quote.
