UNIX for Dummies Questions & Answers

Hello, I'm trying to use grep or egrep to exclude a whole range of characters but how do I exclude both a single and a double quote.

It might be easier to say how do I use grep to find both single and double quotes.

grep ' ' " ' file

grep detects the first single quote within my expression as an end of expression marker.

I've tried backslashing single quotes and double quotes without a happy result.

Code:

matt@devlinux  [/home/matt/contrib]$ cat file
'
"
matt@devlinux  [/home/matt/contrib]$ grep [\'\"] file
'
"
matt@devlinux  [/home/matt/contrib]$

Code:

grep -e "[\'\"]" file

Thanks.

I finally managed to get my egrep to work, with this help.

egrep "[^a-zA-Z0-9.,:/&{}()-\'\" ÅÄÖÉåäöé ]" <file>

which finds any strange, non-Swedish letters in a file. I did notice that grep seems rather sensitive to where certain pattern matching characters are in the string.

Vino,

Thank you for your correction.
