How to grep for $
I tried to grep the word include $ like "MGMT$DB" , but get the following error in Linux.





Code:
$ grep  "MGMT[\$]DB" test1
Variable name must contain alphanumeric characters.
$ grep  "MGMT$DB" test1
DB: Undefined variable.
$ grep  "MGMT\$DB" test1
DB: Undefined variable.
grep "MGMT[$]DB" test1
Illegal variable name.



What is the correct pattern to grep $?


Thanks,

Try:
Code:
grep \\$

# echo '1
$two
3' | grep \\$
$two

Thanks, it solved the issue for single $ or with prefix; Could I also grep the whole word , like "MGMT$DB" together?


Code:
$ grep MGMT\\$ test1
MGMT$DB
$ grep MGMT\\$DB test1
DB: Undefined variable.
