If you precede a connand with set, you can examine the arguments $1, $2, etc. to verify what arguments the command sees after bash performs the various expansions.

change

Code:

SOURCE="{argomentare,bibliografie,documenti}"
in
SOURCE={argomentare,bibliografie,documenti}

No, already tried:

Code:

samiel@debian:~$ bash -x backup.sh
+ SOURCE='{argomentare,bibliografie,documenti}'
+ TARGET=/media/CORSAIR
++ date +%y-%M-%D
+ date=12-35-08/12/12
+ TAG=backup
+ mount
+ grep -q /media/CORSAIR
+ echo 'Il disco è montato: eseguo il backup'
Il disco è montato: eseguo il backup
++ hostname
+ logger Inizio backup di '{argomentare,bibliografie,documenti}' per debian -t backup
+ rsync -rvu --progress '{argomentare,bibliografie,documenti}' /media/CORSAIR
sending incremental file list
rsync: link_stat "/home/samiel/{argomentare,bibliografie,documenti}" failed: No such file or directory (2)

Ok ... so now I think I am following a little better (sorry it took a while).

So on the command line you use brace expansion to list your multiple directories in the current path. So my suggestion still holds that an array would probably suit.
I do however still think the earlier suggestion of an include or exclude file would make this simpler.

However, the array suggestion would work like so:

Code:

SOURCE=( argomentare bibliografie documenti )
TARGET=/media/CORSAIR

rsync -rvu --progress ${SOURCE[@]} $TARGET

I will let you worry about the rest of your code but you should get the general idea.

whizje · 08-12-2012, 08:37 AM

Or change

Code:

SOURCE="{argomentare/*,articoli/*}"
SOURCE=$(echo {argomentare/*,articoli/*})

Now working !!
Only a last proble. For I've a lot of directories,
I must split comman on more lines. In the script,
the backslash doesn't seem to work:

Code:

SOURCE=( argomentare,bibliografie,cataloghi,condominio,copertine,cratilo, \
dialettica,dizionario,documenti,elisp,ermeneutica,esperienza,ezine,fichte, \
filosofi,guide_debian,guide_latex,guide_linux,guide_php,guide_slackware, \
html4dummies,mail,manuale,mutt4dummies,neopositivisti,noneuclidee,novecento, \
protagonisti,protagonisti_nuovo,public_html,retorica,s4d_project,sabina, \
sacchettino,Scaricati,schelling,scuola,slack4dummies,slackbook,songs,storia, \
tesi,texmf, tin4dummies,tractatus,xindy )

How to splt correctly this variable?

Thanx

No backslash required

The array is happy to use any white space.

As you list is quite large (and potentially growing??) I would urge you to look at the include file idea.

samiel · 08-13-2012, 12:21 PM

However

Code:

#!/bin/bash

SOURCE=( argomentare,bibliografie,cataloghi )
TARGET="/media/CORSAIR"
rsync -rvu --progress ${SOURCE[@]} $TARGET

works fine, while

Code:

#!/bin/bash
SOURCE=( argomentare,bibliografie,cataloghi,condominio,copertine,cratilo,
dialettica,dizionario,documenti,elisp,ermeneutica,esperienza,ezine,fichte,
filosofi,guide_debian,guide_latex,guide_linux,guide_php,guide_slackware,

tesi,texmf, tin4dummies,tractatus,xindy )
TARGET="/media/CORSAIR"
rsync -rvu --progress ${SOURCE[@]} $TARGET

give me this error:

I did not notice previously, but you have placed commas in the array and hence rendered it not an array but a single string. Now that you have the new lines
being interpreted as white space it breaks the array into pieces based on the new line. The commas were required when you used {} as this indicates how to expand the
braces in the shell, ie where a word ends, but an array uses white space.

Try replacing all commas with a space. Obviously if any of your file / directory names have a space in them this will cause issues. Again why I would recommend the include file.

samiel · 08-14-2012, 04:19 PM

Perfect.. Now I'll try
with include file too...

Thanx !!

Very strange, I used tthe script but tonight with

Code:

#!/bin/bash
SOURCE=( .abook argomentare bibliografie cataloghi condominio copertine
cratilo dialettica dizionario documenti elisp ermeneutica esperienza ezine
fichte filosofi guide_debian guide_latex guide_linux guide_php guide_slackware
html4dummies mail manuale mutt4dummies neopositivisti noneuclidee novecento
protagonisti protagonisti_nuovo public_html retorica s4d_project sabina
sacchettino Scaricati schelling scuola slack4dummies slackbook songs storia
tesi texmf tin4dummies tractatus xindy .bashrc .vimrc backup.sh )
TARGET="/media/CORSAIR"
rsync -rvuz --delete --delete-after --progress ${SOURCE[@]} $TARGET

I receive

Code:

samiel@debian:~$ sh backup2.sh 
backup2.sh: 2: backup2.sh: Syntax error: "(" unexpected

and don't uunderstand what's happened...

Try placing set -xv as second line in script and check the output.

Also, by calling the script with sh you may limit some of bash's features. Simply make it executable and run it.

konsolebox · 09-01-2012, 01:48 AM

@samiel: I think you mean the use of arrays instead.

Code:

SOURCE=("argomentare" "bibliografie" "documenti") # quotes not necessary unless you have white spaces
rsync -rvu --progress "${SOURCE[@]}" "$TARGET/"
