Top Forums Shell Programming and Scripting Ask for Version of Script on Server w/o download Post 302472071 by al0x on Tuesday 16th of November 2010 07:32:41 AM
Old 11-16-2010
I'm sorry t say this, but my code is still causing trouble T_T
The first solution doesn't work because I need to write every output in a logfile, if I'm trying to do it like this:
Code:
wget -N -t 0 http://somesite/somefile 2> "$TMP"
$TMP >> logfile

I'm getting an error "Permission denied"...
It works well and recognizes that there's no new update but I still need to write everything in a logfile >_>

[edit]: I forgot to mention: I got several update procedures in one logfile, so it's not possible to grep "Not retrieving" out of it :/

[edit2]; Silly me... solved it ^^
Code:
TMP=/some/where/tempfile.txt
wget -N -t 0 http://somesite/somefile 2> "$TMP"
$TMP >> logfile
if cat $TMP | grep -q "Not retrieving"
then
     echo "Theres no newer version..."
else
     echo "New File downloaded!"
fi

Works perfect Smilie

BOOTLOGD(8)						Linux System Administrator's Manual					       BOOTLOGD(8)

NAME
bootlogd - record boot messages SYNOPSIS
/sbin/bootlogd [-c] [-d] [-r] [-s] [-v] [ -l logfile ] [ -p pidfile ] DESCRIPTION
Bootlogd runs in the background and copies all strings sent to the /dev/console device to a logfile. If the logfile is not accessible, the messages will be kept in memory until it is. OPTIONS
-d Do not fork and run in the background. -c Attempt to write to the logfile even if it does not yet exist. Without this option, bootlogd will wait for the logfile to appear before attempting to write to it. This behavior prevents bootlogd from creating logfiles under mount points. -r If there is an existing logfile called logfile rename it to logfile~ unless logfile~ already exists. -s Ensure that the data is written to the file after each line by calling fdatasync(3). This will slow down a fsck(8) process running in parallel. -v Show version. -l logfile Log to this logfile. The default is /var/log/boot. -p pidfile Put process-id in this file. The default is no pidfile. BUGS
Bootlogd works by redirecting the console output from the console device. (Consequently bootlogd requires PTY support in the kernel con- figuration.) It copies that output to the real console device and to a log file. There is no standard way of ascertaining the real con- sole device if you have a new-style /dev/console device (major 5, minor 1) so bootlogd parses the kernel command line looking for con- sole=... lines and deduces the real console device from that. If that syntax is ever changed by the kernel, or a console type is used that bootlogd does not know about then bootlogd will not work. AUTHOR
