Is there anything ‘s/^old$/new/g’ in regexp @rahard
Regex untuk baca #kultwit berurutan & menomerinya: cat file | grep “hashtag” | nl -s”||” | sort -nr | awk -F “\|\|” ‘{print $2}’ | nl -s”.”
I can’t believe I filtered serial tweet with regexp `cat tweet | nl | sort -nr | more | awk -F ‘[0-9]‘ ‘{print $2,$3,$4}’ > tweet`
