Neither xclip nor xsel in the following directory

I just finished to made some modifications on a script and I tried to execute it on terminal with Python but the terminal prompts the following:

which: no xclip in (/usr/local/bin: /usr/bin: /bin: /usr/local/sbin: /usr/sbin:/sbin:/home/myUser/bin)

which: no xsel in (/usr/local/bin: /usr/bin: /bin: /usr/local/sbin: /usr/sbin:/sbin:/home/myUser/bin)

This is the following script that I am trying to execute:

import random, sys, CipherEncryptionP

def main():
    random.seed(42)
        for i in range(20):
        message       = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'*random.randint(4,40)
        message       = list(message)
        random.shuffle(message)
        print('Test #%s: "%s..."' % (i+1, message[:50]))
        for key in range(1,len(message)):
            encrypted = CipherEncryptionP.encryptMessage(message,key)
            print('Transposition cipher test passed. ')

if __name__=='__main__':
    main()

Finally, this is the CipherEncryptionP script that you need to run the code from above.

import pyperclip

def main():
    message        = raw_input("Give me your message: ")
    keyValue       = int(raw_input("Give a numeric value: "))
    ciphertext     = encryptMessage(message,keyValue)
    print(ciphertext + '|')
    pyperclip.copy(ciphertext)

def encryptMessage(message,keyValue):
    ciphertext=['']*keyValue
    for column in range(keyValue):
        pointer= column
        while pointer < len(message):
            ciphertext[column]+=message[pointer]
            pointer+=keyValue
    return ''.join(ciphertext)

if __name__== '__main_':
    main()

I am running a Scientific Linux 6.2 with kernel version 2.6.32-431.1.2.el6.x86_64 and the Python version is 2.6.6. You can download the pyperclip from the following page: http://invpy.com/pyperclip.py.

This first code is used test the second code which is a transposition cipher that I downloaded from http://inventwithpython.com/hacking/chapter10.html.

All suggestions and modifications are welcome :)

I found the following package that installed xclip and xsel in my computer.

rpm -ivh xclip-0.12-1.el6.rf.i686.rpm

Make sure to yum the following packages, otherwise, the above package will not be installed.

yum -y install libc.so.6

yum -y install libXmu.so.6

However, my program still is not executed by python because it appears the following address:

/usr/bin/xclip

Edited on February 3

Finally my program worked and I found out that the problem was the first code.

import random, sys, CipherEncryptionP
random.seed(42)
    for i in range(20):
    message       = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'*random.randint(4,40)
    message       = list(message)
    random.shuffle(message)
    print('Test #%s: "%s..."' % (i+1, message[:50]))
    for key in range(1,len(message)):
        encrypted = CipherEncryptionP.encryptMessage(message,key)
    print('Transposition cipher test passed. ')

I don't know what's the problem with the main function that I had at the beginning but this new fix definitely solved my problem.

Editer on February 3

At the end I discovered that the main function was missing an underscore, so I was able to run my program with that small fix. The problem was solved.

According the comments you don't have xclip or xsel installed. You can check what packages provide them with:

yum whatprovides xclip

outputs: xclip .... Do the same with xsel.

To install them both:

sudo yum install xclip xsel

To get the full path to the executable:

whereis -b xclip

or

which xclip

In case you don't have a repository that provides xsel/xclip you'll need to setup one. Here is an example: http://www.cyberciti.biz/faq/fedora-sl-centos-redhat6-enable-epel-repo/. On my CentOS Epel repo provides xsel.
