Finding executable files linux

How to Execute Files in Linux

Executing files isn’t as simple in Linux as it is in Windows. Many files that are designed to run in Linux aren’t naturally executable, because they don’t have the right permissions. And some files must be executed in the terminal with special commands. If you’re receiving an error that your file isn’t executable, these tips may help.

Mark the File as Executable

Marking a file as executable sometimes requires that you change its permissions. Here, you can use the chmod command. For example:

Run the File from the Terminal

Certain types of executable files, such as shell scripts, must be executed in a different way than other types of files. You must change into the directory where the file is stored to do this properly. For example:

This will run the autogen.sh program, if it has been marked as executable.

Change Execute Permissions from the GUI

You can mark some files as executable within the GUI. Start your favorite file manager, then navigate to the desired program. Right-click the program, then select the “Permissions” tab.

Under Execute, change the permissions to the desired value, such as Only Owner, Only Owner and Group, or Anyone.

Run the File from the GUI

Some executable files will run if you click on them in the GUI. Simply open your file manager and double click on the file.

If you can’t find the executable file that you’re looking for, it may be hidden, or in a hidden folder. Your file manager probably has a menu item or shortcut to show hidden. In my file manager, PCManFM, the Show Hidden option is in the View Menu.

How To Compiling C Program And Creating Executable File Under a Linux / UNIX / *BSD

H ow do I compile C program and create an executable file under Linux or UNIX operating systems?

Tutorial details
Difficulty level	Easy
Root privileges	No
Requirements	C compiler
Est. reading time	5m

[/donotprint]But you can use gcc command to compile program. First make sure you have gcc C compiler installed:

Make Sure Compiler Is Installed On a Unix-like System

Type the following which command or type command or command command to verify that gcc is installed:
$ type -a gcc
$ command -V gcc
$ which gcc
Sample outputs:

Find out version of gcc, run:
$ gcc —version
Sample outpust:

Syntax

The syntax is as follows to compile a C program on a Unix-like operating system:
gcc program.c -o program-output
OR
cc program.c -o program-output
OR
make program

Writing Your First C Program Under a Linux / UNIX-like system

Use a text editor such as vi or gedit or nano to create a C program called first.c:
$ vi first.c

How Do I Compile My C Program?

To compile C program first.c, and create an executable file called first, enter:
$ gcc first.c -o first
OR
$ cc first.c -o first
To execute program first, enter:
$ ./first
Output:

However, both FreeBSD and Linux support direct make (GNU make utility to maintain groups of programs) command on C program without writing a make file. Remove, first program using the rm command:
$ rm first
$ make first

Output:

Execute program first:
$ ./first
Please note that above hack works with GNU/make only.

Your c code is missing the filename of the #include directive.

Thanks for heads up.

Hi, I was just wondering how would you create an executable for numerous C programs? I am modifying the Windows Frotz interpreter for a college assignment with the aim to output the game data to a html page. The source for the interpreter contains numerous C files in a number of subdirectories. I have made the modifications but need to create the executable to see if it works properly. This is my first time creating an executable so i’m a bit unsure how to go about it. Any help would be greatly appreciated.

I just want to thank you. I am 57 years old and I just started computing two years ago. I have built three towers, which is no big deal; but, I have been running a lot of different systems. I want to learn c and c++ and you have helped me a lot. I am grateful for any help I can get. I usually do stuff on my own.I still wonder what the greatest difference is between BSD and Debian other than software installation. I do think that BSD is closer to being pure UNIX than Debian, but the kernels are so alike or an I wrong? It world be nice to know. Anyway, this letter is to thank you.

Nice to see at 57, you are learning BSD and C/C++ development.

*BSD is under BSD vs Linux is under GPL License
Network stack

Little change in command syntax for few utilities

A BSD and Linux kernel are different and follows different development methods and approach.

Please see this post along with discussion for more info.

i want a C program Compiler Code In VI editor

hi, i ve installed red hat linux.and trying to compile C++ prg.but getting a err msg saying that gcc not found.then i tried to see which compiler installed on my linx.To do so i am giving cmd – which
gcc – output is /usr/bin/which: – no gcc.

and i am not able to compile my prog..

plz help me in dis regard.

You need to install install update your repositories, and install it thru the RPM comander or do it with de packgesmanager.

install g++ . in redhat and centos or fedora yum install g++

king777 – you need to make sure the gcc development package is selected when you install redhat. Otherwise, you have to download/install gcc manually.

i don’t know about software creation iam from a village school of india
shall you pls send any program in c for me iam too interest in these

If using the Unix system

Follow the below steps:
$ vi welcome.c
Save the content written below (This is called programme)

include
int main(void)
<
printf(“WELCOME TO THE WORLD OF C\n”);
return 0;
>

Step 3 ) comiple the progamme
gcc welcome.c -o WELCOME

Step 4) For execution
$ ./WELCOME

THNX. very useful. 😀 😀 😀

After typing the following command “$ which gcc” to verify that gcc is installed, the Output was “/usr/bin/which: no gcc in (/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/omar/bin)
” , instead of being “/usr/bin/gcc”. what i have to do now?

I would like to thank you very much. I am new user of linux and C language, I was trying to compile a small program for hours. You made it so easy thank you again and god bless you.

Many thanks for this! I love programming in C and perl and getting my feet wet with Linux/UNIX.

As a followup question, how would I take a program I’ve created (a calculator, for example), and package it so it can run as an executable on another computer (or even embed in a linux distro)?

i want to know how to create executable file.

when u compile any *.c file automatically the executable file is created, which is linked to ld further to get the output,the executable file created after compiling is called as intermediate object file or executable

I file con be executable thru the permitions

–> how we can load and open the serial port in program??
–>how can i open the camera on linux?
–>and how we can comunicate with other laptop with wi-fi?

I followed the steps mentioned above.I m able to compile the code.But when i m givin “./first” to
run it its giving the following “-bash: ./first: Permission denied”. Please help me

Usually the compiled programm. If that’s not the case run
sudo chmod u+x
which gives the user permission to execute the file.

Please someone help me out……

I would like to know how can I execute the file “first” without using preceeding it
with the characters “./” . Any help is appreciated.

when i try to compile a C pogram in centos 5.2…i get the following error
$ cc prog.c
bash: cc: command not found

how to get rid of this prob…pls help

actually it is because gcc is not installed so type “yum install gcc” if u have a centos or fedora

i tried it as su -c’yum install gcc’
but it also get faliure.to install the gcc so hw could i hv 2 go for install.

yum only works if you have a yum repository… otherwise you have to do it manually..

when i try to compile a C pogram in Fedora 13 .i get the following error
$ cc prog.c
bash: cc: command not found
how to get rid of this prob…pls help

Dear friend,
I cannot also create,compile & execute C program in Fedora 15.Please help me to do this mailing me the required commands.

I can’t not compile program

TopDollar !! 🙂
My first c-compilation yummie!
And it works perfect following your instructions.
Peace out!

hi friends can any one say me how can i add libraries(.h) to my gcc compiler

This really doesn’t help me to understand how to make the compiled program executable. When I say executable I mean a *.exe file that I can call by name (such as typing “first_program.exe” in a terminal & having it execute), or by double clicking in a graphical environment.

Does ANYBODY know how to do THAT?!

Can I use script on Windows XP??

If we have a program with multible *.c or *.h files how do we compile those together? And how do we make this a *.exe file or some sort of exacutable?

i just want to know how to install gcc files in fedora. /

use the following command in terminal (it works for me in fedora 14)
yum groupinstall ‘Development Tools’

This will download (approx 105Mb) of data and automatically install it on your system. the best thing is you dont have to worry about the dependencies 😉
then type gcc and press enter
you should get this error “no input files selected” this means gcc is installed.

i tried but it says that you need to be root to perform this command. now what should i do?
