hey guys lets say i have a folder (on linux throw ssh/scp) and there's 10 files in there how do i add them to there own rar files?

the only way i know is

Code:

rar a -s -m5 file.rar *

but this put all files into 1 archive and i want each files to have it's own archive

any help would be very appreciated

If you want to rar each file in the specified directory you can use a script like this:

Code:

#!/bin/sh
for i in $(ls ssh/scp |cut -d"/" -f1);do
echo $i
rar a -s -m5 ssh/scp/$i.rar ssh/scp/$i
done

thanks so much for helping but that just gave lots of errors

also why did you include ssh/scp in the script i didn't mean that was a folder when i said it i was meaning well.. ssh/scp lol

wait a min this is working file after i edited it to

Code:

#!/bin/sh
for i in $(ls rar |cut -d"/" -f1);do
echo $i
rar a -s -m5 rar/$i.rar rar/$i
done

rar is the folder containing the files and it works now BUT only for files without spaces in them?

Say you have a directory with these files:

Code:

% ls
five  four  seven file.dat  six.png  three.txt  two.txt

You might do it like this:

Code:

% for f in *; do rar a -s -m5 "$f.rar" "$f"; done
[a lot of output]
% ls *.rar
five.rar  four.rar  seven file.dat.rar
six.png.rar  three.txt.rar  two.txt.rar

Note that there is a file called "seven file.dat" - note that the file has a space in the name. Because of this, you must quote the expensions of the f variable else the rar command will see separate strings for "seven" and "file.dat". It is generally good practise to quote your variable expansions for this reason.

thank you, thank you, thank you!!!!

any chance you know how to remove the original extension so file.txt becomes file.rar and not file.txt.rar ?

matthewg42 · 10-24-2007, 03:24 AM

Yes. In bash you can use this syntax to remove a suffix from a variable's value: ${variablename%pattern} where pattern is a glob pattern to be removed. For example:

Code:

f=myfile.ext
echo "without extension ${f%.*}"

So the original command would change to:

Code:

% for f in *; do rar a -s -m5 "${f%.*}.rar" "$f"; done

To see other similar variable expansions, see the Parameter Expansion section of the bash manual page.

thank you so much one last thing if you know how to do it

lets say i have a folder with 10 random files in "/home/steve/rar" and i have a readme.txt file located at "/home/steve/readme.txt" is there anyway you can edit that command so that when every file that in the folder gets archived into it's own rar file it includes the readme.txt file as well?

i promise this is the last ting lol

matthewg42 · 10-24-2007, 03:45 AM

Sure, just add that file after the "$f". The syntax of rar is helpful here as it does not include the path of the file by default. A happy co-incidence

Code:

% for f in *; do rar a -s -m5 "${f%.*}.rar" "$f" /home/steve/readme.txt; done

steve51184 · 10-24-2007, 03:47 AM

dude you've main my day so much easier thank you!!!

steve51184 · 10-24-2007, 03:51 AM

forget this post.. again thank you!

right that works fine but there's one thing

when i open the rar that is made i have the file.exe file (one of the random files) then i have a folder called home then in that folder i have a folder called steve then i have my readme.txt file so the rar is saving the path in the folder names but how do i stop this so it's just the 2 files?

nm got it:

Code:

for f in *; do rar a -dp -s -m5 "${f%.*}.rar" "$f" /home/steve/readme.txt; done

matthewg42 · 10-24-2007, 03:00 PM

Oh, it didn't do that for me. What rar version/implementation are you using?

steve51184 · 10-24-2007, 04:23 PM

rar 3.60 but i fixed it with the -dp switch
