True, it is pretty obscure. Bash thinks of everything in tokens, and
only evaluates things once. Usually a token is separated by a space,
but putting quotes (") around the string changes that rule. So take
the example below
AVARIABLE="this is"
VAR="$AVARIABLE \"a string\""
bash goes through and evaluates VAR *once* according to it's rules
which, in this case leaves VAR looking like (tokens separated by a |)
|this|is|"a|string"|
you need to "re-evaluate" this to convert it to
|this|is|a string|

No, bash will convert that to ""Temporary Internet Files"" which is
also wrong.

yes, because \"this is a spacy name\" will be evaulated by bash and
hence form a single token.

Re: [SLUG] Prblem with bash and rsync
have you tried --exclude 'Temporary Internet Files' ? I don't think escape characters will work the way you want in a bash script. the other way to exclude it send it to an exclude file which will cut down the command line to something a little more managable. > > all, > > I have a weird problem with a bash script and rsync (its a snapshot style > backup script). > > Somewhere in the script I create the command: > > ... > ... > COMMAND="$RSYNC -rlptgoD --delete --delete-excluded --exclude .snapshot > --exclude \"Temporary Internet Files\" /$d/ $TARGET" > if [ $DEBUG == 1 ]; then $ECHO $COMMAND; fi > $COMMAND > ... > ... > > Now if I execute the command (which is displayed by the debug statement) using > copy and paste into a XTERM it works. > If I take out the --exclude "Temporary Internet Files" it works. > > But if I run the command through the script I get: > > Rsyncing /home/rsa/ /root/test/home/rsa/hourly.0 > /usr/bin/rsync -rlptgoD --delete --delete-excluded --exclude .snapshot > --exclude "Temporary Internet Files" /home/rsa/ /root/test/home/rsa/hourly.0 > link_stat "/usr/local/backup/Internet" failed: No such file or directory > IO error encountered - skipping file deletion > rsync error: some files could not be transferred (code 23) at main.c(633) > Error rsyncing home/rsa > > Now I have tried: > > --exclude \"\"Temporary Internet Files\"\" > --exclude Temporary\ Internet\ Files > --exclude \"Temporary\ Internet\ Files\" > > and many other ways. > > Any ideas anyone > > jobst > -- > do not email me directly, email to this account must come from mailing lists! > all other mail is placed into /dev/null > > "There are three kinds of lies: Lies, Damn lies, and statistics." - Disraeli > > > __, Jobst Schmalenbach, Technical Director >_ _.--'-n_/ Barrett Consulting Group P/L & The Meditation Room P/L > -(_)--(_)= +61 3 9532 7677, POBox 277, Caulfield South, 3162, Australia > -- > SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ > Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html > -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] Prblem with bash and rsync
all, I have a weird problem with a bash script and rsync (its a snapshot style backup script). Somewhere in the script I create the command: ... ... COMMAND="$RSYNC -rlptgoD --delete --delete-excluded --exclude .snapshot --exclude \"Temporary Internet Files\" /$d/ $TARGET" if [ $DEBUG == 1 ]; then $ECHO $COMMAND; fi $COMMAND ... ... Now if I execute the command (which is displayed by the debug statement) using copy and paste into a XTERM it works. If I take out the --exclude "Temporary Internet Files" it works. But if I run the command through the script I get: Rsyncing /home/rsa/ /root/test/home/rsa/hourly.0 /usr/bin/rsync -rlptgoD --delete --delete-excluded --exclude .snapshot --exclude "Temporary Internet Files" /home/rsa/ /root/test/home/rsa/hourly.0 link_stat "/usr/local/backup/Internet" failed: No such file or directory IO error encountered - skipping file deletion rsync error: some files could not be transferred (code 23) at main.c(633) Error rsyncing home/rsa Now I have tried: --exclude \"\"Temporary Internet Files\"\" --exclude Temporary\ Internet\ Files --exclude \"Temporary\ Internet\ Files\" and many other ways.
