Full Discussion: How to manipulate the conditions between every retry in wget?
Top Forums UNIX for Advanced & Expert Users How to manipulate the conditions between every retry in wget? Post 302618155 by Corona688 on Tuesday 3rd of April 2012 04:44:10 PM

I repeat -- you can't do what you want that way. wget isn't a programming language. It can't understand "if x do y, if z quit".

The code I gave you does what you want. It doesn't use wget's own retry feature, but runs wget repeatedly with single tries.

To make it clearer, perhaps this:

Code:
TRIES=1

while ! wget --tries=1 http://url/
do
        case "$TRIES" in
        1)     # First failure.
                # if xxxx is in logfile, try again.
                grep -q xxxxx /path/to/logfile || break
                ;;
         *)   # Second and further failures.  Break the loop.
                break
                ;;
        esac

        TRIES=`expr $TRIES + 1`
done

plucker-prc-install

plucker-prc-install(1)					      General Commands Manual					    plucker-prc-install(1)

NAME

       plucker-prc-install - fetch and install Plucker viewer application on a Palm pilot

SYNOPSIS

       plucker-prc-install [options]

DESCRIPTION

       This  manual page documents briefly the plucker-prc-install command.  This manual page was written for the Debian distribution because this
       program was created for the Debian package.

       plucker-prc-install is a program that fetches and installs the Plucker viewer application.

       The program uses wget to get the .tar.bz2 archive from the Web. You need to be connected to the Internet and have wget working correctly in
       order  to  use this program. You may have to configure the environment variable http_proxy. You can take a look at the lynx command manpage
       to get information about http_proxy.

       The program tries to use the correct language version of the viewer according to the environment variable LANG.

       The program then uses either gpilot-install-file or pilot-xfer to transfer the three .prc files to the Palm pilot.

       With pilot-link 0.12.x it is mandatory to provide a port to use.  plucker-prc-install first use the  value  of  the  PILOTPORT  environment
       variable. If PILOTPORT is not defined it uses /dev/pilot. If the file /dev/pilot does not exist it uses usb:.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').  A summary of options is included
       below.

       --nohires
	      installs the low-resolution version of the Plucker viewer. If you are using a Palm with a 160x160 screen (Palm m500-series and  ear-
	      lier)  you  can  save  approximately  90 KB by installing the low-resolution version of the viewer. Note that the hires version will
	      still work on older Palms, but will just take up unnecessary space.

       -h, --help
	      Show summary of options.

       -v, --version
	      Show version of program.
