HOWTO make a script to compress directories, Not yet solved

[pieniValkoinenHattu]

Hello,

I would like to know how to make a script to compress all the directories contained in a parent directory.
To be clear I would like a way to do something like that:

for directory from firstDirectory to lastDirectory do
zip directory //the name of the zip should be the same as the directory
end

Thank you.

Not exactly entirely clear what you want.

To compress a dir recursively:

CODE

zip -r output.zip mydir

To compress all dirs separately in a parent dir:

CODE

ls PARENTDIR | while read MYDIR; do zip -r MYDIR.zip MYDIR; done

or

CODE

find PARENTDIR -type d | while read MYDIR; do zip -r MYDIR.zip MYDIR; done

My script looks like this (lbzip2 uses all CPU cores):

CODE

#!/bin/bash # COMPRESS FILE OR DIRECTORY FILE="$1" FNAME=`basename "$FILE"` if [ -z "$FILE" ]; then echo "usage: command [dir|file]"; exit 1; fi if [ -d "$FILE" ]; then        SIZE=`du -sb "$FILE" | cut -f1`        tar -cf - "$FILE" 2>/dev/null | pv -s "$SIZE" | lbzip2 > "$FNAME".tar.bz2 else        pv "$FILE" | lbzip2 > "$FNAME".bz2 fi

Thank you very much for answering however I don't know how to use what you wrote.

To be more precise I would like some kind of loop that compress each directory contained in a directory for exemple:

CODE

[isen@ISENMIC-EU0I8NA Family]$ ls Brother  Father  Me  Mother  Sister

I am in the folder Family and I want to have one zip file for each directory it contains ( Father.zip, Mother.zip etc...)

So you go with the command starting with the find command. Stand in your Family directory, and run it.

Sorry for being such a noob but it does not work:

CODE

[isen@ISENMIC-EU0I8NA Family]$ find ../Family/* -type d | while read MYDIR; do zip -r MYDIR.zip MYDIR; done zip warning: name not matched: MYDIR zip error: Nothing to do! (try: zip -r MYDIR.zip . -i MYDIR) zip warning: name not matched: MYDIR zip error: Nothing to do! (try: zip -r MYDIR.zip . -i MYDIR) zip warning: name not matched: MYDIR zip error: Nothing to do! (try: zip -r MYDIR.zip . -i MYDIR) zip warning: name not matched: MYDIR zip error: Nothing to do! (try: zip -r MYDIR.zip . -i MYDIR) zip warning: name not matched: MYDIR zip error: Nothing to do! (try: zip -r MYDIR.zip . -i MYDIR)

I don't know what should I put instead of MYDIR, (I replaced the PARENTDIR by ../Family/* because other way it didn't work at all: not found directory )

No problem, I said it incorrectly. Stay inside your Family dir, and run it with "find . -type d ...." with an extra options like this:

CODE

find . -maxdepth 1 -type d | sort | tail -n+2 | while read MYDIR; do zip -r "$MYDIR".zip "$MYDIR"; done

I tested it and it seems to be working just fine.

Thank you so much, this is awesome !

Could you explain me the line ?
I would like to be able to make script like this one on my own.

Thanks again !

man find
man sort
man tail

besides, try the script in parts, like:

CODE

find . -maxdepth 1 -type d

CODE

find . -maxdepth 1 -type d | sort seq 1 10 seq 1 10 | shuf seq 1 10 | shuf | sort

CODE

seq 1 30 | tail seq 1 10 | tail -n2 seq 5 | head -n 2

etc.
