Basic Shell Commands

To speak about the truth, I actually don’t dislike Linux, but i don’t feel comfortable on it. But i am feeling it is going to be important day by day specially in developer society (I don’t know, home user will ever choose Linux for their every day computing). I am learning some shell commands (they are not many but TOO many!!) here i listed some basic commands (just for me):

cd—Changes directories
chmod—Changes file access permissions
cp—Copies files
du—Prints disk usage
find—Finds files by searching
grep—Searches for a string in input
less—Filter for paging through output
ln—Creates links between files
locate—Finds files from an index
ls—Lists files in the current directory
make—Compiles and installs programs
man—The manual page reader
mkdir—Makes directories
mv—Moves files
ps—Lists processes
rm—Deletes files and directories
ssh—Connects to other machines
