I found lot of definitons for quotemeta in perl,but i am still confusing that why we have to use that and how to use it.I never found any example regarding this.
The definition is like thisz"Returns the value of EXPR with all non-"word" characters backslashed. (That is, all characters not matching
will be preceded by a backslash in the returned string, regardless of any locale settings.) This is the internal function implementing the \Q escape in double-quoted strings"
can anyone let me know how i have to use this.
