htr is a custom command that will restart apache
echo "service httpd restart" > /usr/bin/htr ; chmod 700 /usr/bin/htr
awstats is a custom command that will update ALL STATS for all sites that have a config file
echo "/usr/local/awstats/tools/awstats_updateall.pl now" > /usr/bin/awstats ; chmod 700 /usr/bin/awstats
mail-ps is a custom command to mail the current process list to statusupdate@xxxxxxx.net
echo "ps auxw | mail -s \"Server: Current Processes\" statusupdate@xxxxxxx.net" > /usr/bin/mail-ps ; chmod 700 /usr/bin/mail-ps
mail-netstat is a custom command to mail the current open port list to statusupdate@xxxxxxx.net
echo "netstat -nape | mail -s \"Server: Current Active Internet Connections\" statusupdate@xxxxxxx.net" > /usr/bin/mail-netstat ; chmod 700 /usr/bin/mail-netstat
htr is a custom command that will restart apache
echo "service httpd restart" > /usr/bin/htr ; chmod 700 /usr/bin/htr

Change Permissions of files (chmod)
Here's another from my scrap notes.
chmod 000 filename.abc
(defaults are usually 755 for folders, 644 for files)
Numbers correspond to users. 1st=Owner; 2nd=Group; 3rd=Other
(-rwxrwxwrx = 777, -rwxr-xr-x = 755, -rw-r--r-- = 644, etc.)
7 = Read + Write + Execute
6 = Read + Write
5 = Read + Execute
4 = Read
3 = Write + Execute
2 = Write
1 = Execute
0 = All access denied

qmail
Flush the queue and send all mail
killall -ALRM qmail-send
I use this every now and then on my failover mail queue.

Common Linux Commands I Use
Processes
To view current processes running on the system use the following commands:
ps auxw # USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
ps auxw | grep | sort –n
Netstat
To view open connections and ports use netstat.
Netstat –nape
Outputting to Null
> /dev/null
TAR
To tar a file:
tar -cf nameOfTar.tar Folder1 Folder2
To untar a file
tar -xvf nameOfTar.tar
To untar a gzip file
tar -zxvf nameOfTar.tar.gz
Touch
A simple command that can create a file quickly
touch /var/log/somelogname.log
chmod 700 /var/log/somelogname.log
echo “this is a log file” > /var/log/somelogname.log
cat /var/log/somelogname.log
HTTPD Restart
/etc/init.d/httpd restart
Server Version
cat /etc/redhat*
CentOS release 4.5 (Final)
2)On SUSE Linux,
$cat /etc/SuSE-release
Top
Top displays a lot of system information in real time. CPU/memory/etc. It is a resource hog though.
top
Free Memory
free –m // memory
FTP
ftp server.com
use ftp -i server.com to remove confirmations. For example, downloading multiple files requires the use of mget *.*. Without logging in with -i it will force you to acknowledge the download of each file.
Reboot
shutdown -r now is reboot
Nice
Usage: nice [OPTION] [COMMAND [ARG]...]
Run COMMAND with an adjusted scheduling priority.
With no COMMAND, print the current scheduling priority. ADJUST is 10
by default. Range goes from -20 (highest priority) to 19 (lowest).
-n, --adjustment=ADJUST increment priority by ADJUST first
--help display this help and exit
--version output version information and exit
Example:
cd /; nice -n 15 /usr/bin/clamscan -r | mail -s "Server: AV Scan Results" chad@xxxxxxxxxxxx.com
Display resources
cat /proc/user_beancounters
egrep "failcnt|numiptent" /proc/user_beancounters
httpd configtest
/etc/init.d/httpd configtest
To view current processes running on the system use the following commands:
ps auxw # USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
ps auxw | grep
Netstat

Getting Subversion 1.5.7 installed on Cent OS 4.8.
This is for my personal notes as I could not find a repo for yum that had Subversion 1.5.7. RPMForge has 1.4.6 currently for Cent OS 4. Also, this install is on Mediatemple's DV.
Search for current versions
Returns something like the following:
Remove current versions
Get new version and install
Make a hard link to the new location of svn fom our bin directory
Check Version
Search for current versions
rpm -qa | grep -i subversion
Returns something like the following:
subversion-1.4.6-0.2.el4.rf
Remove current versions
rpm -evf mod_dav_svn-1.4.6-0.2.el4.rf
rpm -evf subversion-1.4.6-0.2.el4.rf
Get new version and install
curl -O http://subversion.tigris.org/downloads/subversion-1.5.7.tar.gz
curl -O http://subversion.tigris.org/downloads/subversion-deps-1.5.7.tar.gz
tar xzvf subversion-1.5.7.tar.gz
tar xzvf subversion-deps-1.5.7.tar.gz
cd subversion-1.5.7
./configure --prefix=/usr/local --with-openssl=/usr/bin --with-ssl
make
make install
Make a hard link to the new location of svn fom our bin directory
