Hello

I'm a newbie 2 linux and have managed 2 install and put linux on network/internet.

My Question:How can i know whether i have a C compiler installed or not.If it's installed what are the commands to run the complier,compile the code and execute the program(everything).Like in windows i can do everything with a click.

Thank you.

Here are some handy commands I have collected

Handy bash commands for finding out stuff in Linux:
# Find CPU specifications
cat /proc/cpuinfo

# Find running kernel version
uname -r

# What compiler version do I have installed
gcc -v
gcc --version

# What is the running kernel and compiler installed
cat /proc/version

# Find X server version
X -showconfig

# What pci cards are installed and what irq/port is used
cat /proc/pci

# Memory and swap information
cat /proc/meminfo
free
An article: Tips for Optimizing Linux Memory

# How are the hard drives partitioned
fdisk -l

# How much free/used drive space
df -h

# Show disk usage by current directory and all subdirectories
du | less

# What takes up so much space on your box
# Run from the directory in question and the largest chunk shows up last
find $1 -type d | xargs du -sm | sort -g

# What is the distribution
cat /etc/.product
cat /etc/.issue
cat /etc/issue
cat /etc/issue.net
sysinfo

# For finding or locating files
find
locate
which
whereis

# Use dmesg to view the kernel ring buffer (error messages)
dmesg | less

# Watch error messages as they happen (sysklog needed)
as root, tail -f /var/log/messages (shows last 10 lines, use a number in front of f for more lines)

# What processes are running
ps -A

# Find a process by name
ps -ef | grep -i <plain text>
For example, XCDroast
ps -ef xcdroast

# See current environment list, or pipe to file
env | more
env > environmentvariablelist.txt

# Show current userid and assigned groups
id

# See all command aliases for the current user
alias

# See rpms installed on current system
rpmquery --all | more
rpmquery --all > <filename>
rpmquery --all | grep -i <plaintext>

Autospec for tarballs
RPM tools

# What directory am I using
pwd

# Get ls colors in less
ls --color=always | less -R

Look at man <command> or info <command> for the flags I used and for other options you can use for bash commands.

Well.. save your C source code in an ordinary text file with a .c extension ie

sourcefile.c

then - on the command line cd into the directory which the source file is in then:

gcc sourcefile.c -o executable_name

and to run it try

executable_name

or

./executable_name

or move it into your PATH (depending on circumstances)

(you can always

chmod 755 path_to_sourcefile.c

etc etc to have more control on permissions)
