Problem with grep and regular expresions 1

[jmiturbe]

Hello,

I`m trying to write a shell script that parses email addresses. The problem is that my script treates the dot on email addresses as a wilcard, so it matches more addresses than really needed.

Does anybody know how to avoid this? Thanks in advance.

escape the metacharacter with a backslash?

\.


Kind Regards

Hi:

I have the same (or similar) problem that jmiturbe. I have a script that asks for an email account and the user inputs it. If this user inserts a email account which has a dot it match more addreses than the really are.

Example:

#script
echo "User account:\c"
read codigo
grep -v ^${codigo} aliases > aliases.tmp; cp aliases.tmp aliases
#script

Have you tried this ?
read codigo
codigo=$(echo $codigo | sed -e 's!\.!\\.!g')

Hope This Helps, PH.

Use fgrep (or grep -F) instead of grep.
