SED Problem (Solved)

[taersh]

Hi.

I'm currently working on a new idea.
Therefore I need to grab the red part of each line within the lines of /root/.jwmrc.

<Program label="Desktop-Symbole wiederherstellen" icon="desktop48.png">/usr/local/puppypin-restore/puppypin-restore</Program>

I'm using

Code: Select all

COMMAND=$(echo $LINE|cut -d'>' -f2)

which returns

Code: Select all

/root/tmp/right-click-actions</Program

I tried to add sed to the above command but whatever I tried, each attempt failed!

Code: Select all

COMMAND=$(echo $LINE|cut -d'>' -f2 | sed 's/</Program//)'

What am I doing wrong here?

In your last example you need to escape the slash in /Program -> \/Program, because you are already using it as a delimiter:

Code: Select all

COMMAND=$(echo $LINE | cut -d'>' -f2 | sed 's/<\/Program//')

or just use a different delimiter, e.g.:

Code: Select all

COMMAND=$(echo $LINE | cut -d'>' -f2 | sed 's#</Program##')

you could also use one more cut, instead of sed:

Code: Select all

COMMAND=$(echo $LINE | cut -d'>' -f2 | cut -f1 -d '<')

Anyway, here's pure sed solution:

Code: Select all

COMMAND=$(echo $LINE | sed -n 's/.*>\(.*\)<.*/\1/p')

Everything within the brackets becomes the variable '1', which is printed in the end.

Disclaimer: I'm not a sed expert, I just often use the above construct.

HTH
Greetings!

Thanks!

Oh my god, since I changed my gtkdialog developments from the use of double quotes to single quotes, I completely forgot this ESCAPE thingy.

However, the one liner code is what I'm using and what solved my problem in complete.
I could finished my purpose of a new Puppy program and tested it successfully.

It will give option to Puppy Linux to place a menu entry to the Rox desktop just by clicking that menu entry.

Package is on the way to be built and then published.

Again thanks!

Another solution:

use 'tr'

Code: Select all

#! /bin/bash
LINE='Program label="Desktop-Symbole wiederherstellen" icon="desktop48.png">/usr/local/puppypin-restore/puppypin-restore</Program>'

FilSpec=$(echo "$LINE" | tr -d "\"" | cut -d'>' -f2 | cut -d'<' -f1)

echo "$FilSpec"

Another solution:

Same as SFR's 3rd solution

use 'tr'

Why?

[Jafadmin]

Why?

[edit] Oh .. you mean why use tr, right? Because the echo command will fail in that instance if the quotes aren't removed ..
Also ....
Less arcane than sed. I find that when I come back to change/update code that the easier it is to read and understand, the quicker I can finish up.

If readability isn't an issue, then it doesn't matter.

Planes have always been my thing when it comes to flight simulations that you can download on pc. I never really found the appeal of helicopters. I have always been in the opinion that they are very clunky and heavy to use. With planes, once you take off from the tarmac you are golden. All you need to do then is check your gauges and you are golden until you land at the destination. That is why when I am done with school, I will train to become a pilot. I have already filled out the application form when you [.

It's spam, so I eliminated it with extreme prejudice! Wiz
