[Solved] A Challenge: Loop meld to update *.pacnew files

Gen2ly · 2009-10-02 16:22:48

I got no secret, I love meld . Does a great job of showing differences alot of times if even scattered all over the page, allows for copy and paste... vimdiff is good but requires a much more keypresses, copy and paste isn't as elegant, and with my fixed drop-down terminal is just too narrow to be able to do it well. So what I usually end up doing is:

find /etc -type f -name "*.pacnew"

and just go through them one at a time:

kdesu meld /etc/config /etc/config.pacnew

I haven't do much work with loops, so I was hoping that someone that knew a little about them that could create a script that would go through them one by one. I suppose this is going to be a little tricker because (I imagine) it's going to have to detect when the windowed instance closes.

From the knowledge I know, I would do:

#!/bin/bash
# etc-update - merge *.pacnew files with original configurations with meld

pacnew=$(find /etc -type f -name "*.pacnew")

for i in $pacnew
do
  kdesu meld $i
done

Which isn't going to work very well. Well, I guess it could, but it's going to open them all at once and leave a nice scruched-up taskbar with *.pacnew files. Like to be able to go through them one by one.

Anyone had any experiences at this that could help?

Maybe....

#!/bin/bash
# etc-update - merge *.pacnew files with original configurations with meld

pacnew=$(find /etc -type f -name "*.pacnew")

for i in $pacnew
do
  kdesu meld $(basename $i .pacmew) $i &
  wait
done

Note - untested

just do a find/replace of vimdiff for meld (or whatever...)

I just edited the pacdiff script to use meld and it worked great : ) -- I am not at home atm, but if you would like I can post up my edited pacdiff script.

pacmew ? Kittens ?

How about

#!/bin/bash
pacnew=$(find /etc -type f -name "*.pacnew")

for i in $pacnew ; do
kdesu meld $i &
while (ps -e | grep ^$! &>/dev/null); do
    sleep 1
done
done

Edit: wait!

Nice one lolilolicon. BTW $! does not expire, so you could use kdesu meld $i & while [ -d /proc/$! ]; do sleep 1; done

i wrote my full script a while back... but in the interest of a find-the-simplest-way challenge i'll post this version of allan's

for file in $(find /etc -name '*.pacnew'); do meld ${file/.pacnew/} $file; done

why do you all send it to the background then wait for it? just leave it in foreground and the loop will wait for you, right?

/edit: screwed up the order
/edit2: nope, had it right the first time...

Nice script, bris. If I had know about that before, I'd be using it. Do like the idea of the walk-through process and the saving of the the current one.

lol, I just read your last post and just what I thought about.

Yeah, I saw that on the wiki. Said it was for CLI though so I didn't get to try.

@ lolilolicon, and Procyon

Still learning about pids, what I have seen was more complicated than this. Pretty clever.

Ah, very nice. Also fits into my knowledge of bash. Hadn't thought about just using & but it works great. Had to truncate the file extension and just used a bash filter:

#!/bin/bash
# pacnew-diff - merge *.pacnew files with original configurations with meld

pacnew=$(find /etc -type f -name "*.pacnew")

for config in $pacnew
do
  kdesu meld ${config%\.*} $config &
  wait
done

Like to be able to do a backup of the current config and then erase the pacnew file afterword, but havn't found out a way to do that without having to type in a password everytime, but, I guess, that can easily be done elsewhere.
