egrep

Using another search engine such as a DFA based Regex engine like egrep, flex, or an appropriate version of awk.

Wait: nip 'function(l) { return /^var/.test(l); }' is supposed to be better than egrep '^var'?

Can you skip the whole writing to file bit, and pipe straight to egrep?

The functionality of fgrep(1) and egrep(1) have largely been merged into more monolithic grep(1) implementations, though the former two remain as aliases.

The ERE described in egrep(1) has backreferences which can match non-regular languages.

Like Java, Intellij Idea Search&Replace, vim, less, grep, egrep, sed.

My problem: I still don't have a good mnemonic to remember how magic differs grep, egrep, vim, awk, Perl, Python, etc.

I mainly use emacs, gcc, g++, git, gdb, plus bash, sed, egrep, tr etc.

./toolkit/devtools/gcli/source/lib/gcli/types/selection.js:81: spec.remoteLookup = (typeof this.lookup === 'function');./toolkit/devtools/gcli/source/lib/gcli/types/selection.js:128: if (this.remoteLookup) { egrep -Rni remotelookup.

But even still - I like to have the text files as journals of original entry - so I can occasionally do a tail -f incoming.log| egrep -i "somedevice".

Case in point, there's a comment here: "Wait: nip 'function(l) { return /^var/.test(l); }' is supposed to be better than egrep '^var'?" Yes, it absolutely is better (except when performance really matters), because it's very easy to see how to extend that to more complex things, whereas I don't know how to extend egrep without doing lots of reading - if it's even possible without switching tools.
