Where are programs like make, gcc, python, etc?

They are all under /usr/ccs/bin and /usr/sfw/bin.

Utilities like whoami are under /usr/ucb

You should set them in your PATH.

Setting up the default gateway under SunOS

Run route add default x.x.x.x and also add the IP to the /etc/defaultrouter file such that it will survive a reboot

This is analogous to route add default gw x.x.x.x under linux.

Extracting a .tar.gz archive

Run gzip -dc File.tar.gz | tar xf - to extract File.tar.gz

This is analogous to tar -xzf File.tar.gz under linux.

The first few lines of the top command looks similar to this:

Tasks: 137 total, 1 running, 136 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0%us, 4.2%sy, 90.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 5.8%st
Mem: 786432k total, 715152k used, 71280k free, 61012k buffers
Swap: 2096472k total, 18304k used, 2078168k free, 168068k cached


The fields on the second line breaks down the CPU usage into 8 categories.

Create a .htaccess file with the following:

Options +Indexes
IndexOptions +FancyIndexing

To ignore certain files, use IndexIgnore:

IndexIgnore *.php

If you are trying to compile RRDTool (at the time of writing, 1.4.5) on CentOS 5.x, you will need install the following packages on yum:

yum install cairo-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel libart_lgpl-devel

Then, just compile rrdtool as usual:

wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.5.tar.gz
tar -xzf rrdtool-1.4.5.tar.gz
cd rrdtool*
./configure --prefix=/opt/rrdtool
make
make install

To merge the standard out and standard error streams from a program, use 2>&1.

Example: umount /adsf/asdf 2>&1 will output the errors into standard out instead of standard error as usual.

Note that:

• 2 is the file descriptor for stderr.
• 1 is the file descriptor for stdout.
• & accepts a file descriptor which can then be treated as a file.

Thus, 2>&1 in turns ‘writes data’ from stderr into stdout.

Here’s a quick way to reset your mysql root password. Replace ‘NewRootPass’ with your new root password and run the following as root.

/etc/init.d/mysql stop
mysqld --skip-grant-tables --user mysql &
mysql -u root -e "UPDATE mysql.user SET Password=PASSWORD('NewRootPass') WHERE User='root'"
/etc/init.d/mysql restart

Note: This was done on CentOS. You might need to adjust the path to mysql’s startup scripts accordingly.
