Linux basics

some linux basics

Basic terminal commands:

commands a-z:

Piping commands:

a bunch of helpful sed one liners

the grep command

chmod (detailed) changing permissions:

chown (detailed) changing ownerships:

bash basics:

(there's alot of redundancy here, but this stuff is everwhere :P)

uncompress a .zip file | unzip -d
uncompress a .tar file | tar vxf file.tar
uncompress a .gz file | gunzip -d file.gz
uncompress a .bz2 file | bunzip2 -d file.bz2
uncompress a .tar.gz file | tar xzvf file.tar.gz
uncompress a .tar.bz2 file | tar xvjf file.tar.bz2

ok, so you just downloaded your 'source.file.compressionformat'
extracted it, now you need to compile it.. (if it calls for being compiled)

cd extractedfilesdir
ls -f, look for documentation like a README or INSTALL or README_FIRST, something to that effect..
and example type: cat README | more
..and read thoroughly, this will give you detailed instructions.

to configure a source
start off with: ./configure --help | more
this will give you the option to enable disable change installation paths so on so forth

so your basic configure would be:
./configure --with-feature=enable --prefix=/usr/local/mysource
then if all goes well:
su -
make install
if all goes well
the source will compile and be installed in /usr/local/mysource

sometimes files are downloaded as 'bin' files
or 'sh'

(be careful with these and make sure the source from which you are obtaining them from is safe )

once downloaded ;
chmod +x filename.bin or
(this makes the file executable)

then type ./filename.bin or ./
(as before there's many different types, these are just the most basic)

This isn't anywhere near what linux is capable of, but you've got to learn to crawl before you walk

..My objective here is to motivate people to learn and use the console
..The most powerful user-interface in linux. It don't have to be pretty to be STRONG! :)
