regex search and replace

regex search and replace

[Gary Wessle]

Hi

I am using GNU emacs 21.4.1 and wanting to use regex to do the
following.

I have few lines in the format 
  -rw-r--r-- 1 fred fred 56823 Oct 14 01:32 samcar
  ...
  -rw-r--r-- 1 fred fred 56823 Oct 14 01:32 manham

I want to end up with 
{ "sam/car", ..., "man/ham" }

so my step by step approach is to remove the 
"  -rw-r--r-- 1 fred fred 56823 Oct 14 01:32 "

then to change aaabbb with aaa/bbb.

then to replace end of line with (", ")

and maybe by then I will learn enough to finish the task.

so, playing around with	incremental regex search and hoping some body
will help me to learn something mean while.

thanks

I was able to reach 
xxx/yyy
.../...
ass/bbb

but when I replace end-of-line with (", ") it still leaves an
end-of-line after (", ").
that is it does not convert the lines to one lone line in the form
xxx/yyy, ...,"aaa/bbb"

the command I used was
replace-regex<ret>$<ret>", "<ret>

thanks

M-x replace-regexp RET ^.*\(\w\{3\}\)\(\w\{3\}\)$ RET "\1/\2" RET

You can find more info on REs here:

> then to replace end of line with (", ")

M-x replace RET C-q C-j RET ,<SPC> RET

EOL is no regular character. You can address it either by this, or by  
C-j.

May be you can use Macro. It could be faster to build , compared to
searching or building regexp.

Use this insted:

replace-regex<ret>C-q C-j<ret>", "<ret>
