less wrapper

Do you find yourself doing a grep -rn through a code base looking for an given log line or function call, then doing a quick less <file>.src followed by a :382 to jump to the relevant line?

Wouldn't it be nicer if you could just open that line directly using the grep -rn output?

The less wrapper script intends to do exactly that, a shorthand and intuitive way to open files.

Any of the below should work as you would expect:

$ less file.ext
$ less file.ext:23
$ less file.ext-24
$ less file.ext 23
$ less file.ext:23:	if [ ...
$ less file.ext-24-		local ...

If you like this then you may want to check out the vi(m) equivalent vi-wrapper.

Example use case

[bash@marklet:~/]
$ grep -rn _LESS_WRAPPER_BIN bashmarklets                                                                                                                                   
bashmarklets/less-wrapper/less_wrapper.inc:7:	if [ ! -z "${_LESS_WRAPPER_BIN}" ]; then
bashmarklets/less-wrapper/less_wrapper.inc:8:		local LESS=${_LESS_WRAPPER_BIN}

[bash@marklet:~/]
$ less bashmarklets/less-wrapper/less_wrapper.inc:8:

How to install

Either download/clone this repository and add the following to your ~/.bashrc file:

source path/to/less_wrapper.inc

or alternatively just copy-paste the function directly into your ~/.bashrc file.

NB: The source approach is recommended if you end up picking up more than one of these bookmarklets as it avoids clutter.
