Is There A Way To Have A Script Called Source, That Can Be Run Without The Full Path?

Is there a way to have a script called source, that can be run without the full path?

Ex:
When I run:
export PATH=/home/user:$PATH
source

I get:
Code:
$ source
bash: source: filename argument required
source: usage: source filename [arguments]

However I want it to run my script called source:
Code:
$ cat source 
#!/bin/bash
echo "Hello World"

Is there way to override a shell builtin in the PATH var or some other way?

Benefit Of Source Command

Hi,

What are the benefits that we get when we choose to source a file rather than execute it as a shell script?

and then in what way is export opposite to source?

It looks like they are doing the same thing, i.e making environment variables accessible in the local shell

Error In Running Leach_test In NS-2.34

Hi all,

I am trying to simulate leach on NS2 but I've had problems with running the leach_test. I've followed all steps from installing NS2 up to installing the LEACH patch (used the latest one from exidus). Here's the error message in the leach.err I found.

Code:
couldn't read file "/mit/uAMPS/uamps.tcl": no such file or directory
    while executing
"source.orig /mit/uAMPS/uamps.tcl"

Your help are very much appreciated, thanks!

I'm New To Linux....questions Compiling A Small Source Code

Hi Everybody.....
I'm new to this site and new to Linux ( Ubuntu 12.04) generally. I am an old goat mechanical engineer with years of electronic instrumentation design experience. I am connecting several of my old HP digital oscilloscopes and logic analyzers to a Ubuntu box via GPIB (ieee 488) interface. I have the interface working well using the open source ( Sourceforge) "Linux-GPIB" kernel module. I can remotely control the instruments using "Linux-GPIB"'s "ibterm" terminal utility. However "ibterm" doesn't provide a means to do a scope screen dump to a file. A guy on EEBLOG published a short C language 30 line source code to perfome this function. Unfortunately it isn't a package with makefile.am, makefile .in, configure etc which I understand I could compile using the typical ./config, make, checkinstall procedure. It is just the c source code text. Soooo.....do I use gcc directly? If so, how do I run gcc in a manner to be able to uninstall all the various files it will make? Or ?? What is the procedure for automake in this situation ? Or....? I'm kind of lost. Your suggestions would be helpful.
Cheers.

Leach Doubt..

Hi. I have some doubts regarding “LEACH” protocol. I’m using ns-2.34 on Ubuntu 10.04 and patched leach protocol by following below link. I got ‘leach.out’ file, but I didn’t get ‘leach.err’ file.

https://abdusyarif.wordpress.com/201...-step-by-step/

Then I want to check out the leach source code file. The source code of the leach is not found in that folder. I ran out the leach test file and I’ve got a warning message.

Iptables --policy (login Slow)

Dear all,

This is my current iptables (with default policy = Accept) and no rules.
Code:
[root@racnode1 ~]# iptables -L -v
Chain INPUT (policy ACCEPT 77072 packets, 7890K bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 70306 packets, 129M bytes)
 pkts bytes target     prot opt in     out     source               destination         
[root@racnode1 ~]#

I have decided to allow only incoming network connection from my own subnet and hence

Code:
[root@racnode1 ~]# iptables -A INPUT -s 192.168.0.0/24 -j ACCEPT
[root@racnode1 ~]# iptables -L -v
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         
  178  9055 ACCEPT     all  --  any    any     192.168.0.0/24       anywhere            

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 186 packets, 316K bytes)
 pkts bytes target     prot opt in     out     source               destination         
[root@racnode1 ~]#

Noted that my default policy is still ACCEPT, hence I

Code:
[root@racnode1 ~]# iptables --policy INPUT DROP

===============================================================

Upon this, I have 2 issues

a) my iptables -L -v command can't display fully, i am stuck at below

Quote:
[root@racnode1 ~]# iptables -L -v
Chain INPUT (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
b) my ssh login is very slow

Quote:
login as: root
-- waited quite sometime before prompting me for password
===============================================================

If i removed revert the INPUT policy to ACCEPT, then everything will be fine as normal.

Why ?

Thanks and look forward to your advises.

Regards,
Noob ;(

Problem With (instalation Of?) Mysql.h On C

Hi, I've just recently installed MySQL connector/c from source code on my Slackware 14.1 x64

I read the official instructions of the connector but I felt a bit disorientated when I read:
Code:
1 -Change location to the top-level directory of the source distribution.

I interpreted that I have to go to the "highest" directory Code:
/

So I wrote: Code:
 
        #                            cd /

root@- /#                            tar xzvf /home/normal/Downloads/mysql-connector-c-6.1.6-src.tar.gz 

root@- /#                            cd /mysql-connector-c-6.1.6-src/

root@- /mysql-connector-c-6.1.6-src# cmake -G "Unix Makefiles"

root@- /mysql-connector-c-6.1.6-src# make 

root@- /mysql-connector-c-6.1.6-src# make install

Then I did:
Code:
ln -s /usr/local/mysql-5.6.25/include /usr/include

But when I try to compile a program in c with #include <mysql.h> i get this error:
Code:
# gcc ctemp.c 
In file included from ctemp.c:2:0:
/usr/include/mysql.h:57:27: fatal error: mysql_version.h: No such file or directory
 #include "mysql_version.h"
                           ^

What can I do? Thanks a lot and sorry for poor english

PD: If you need the official instructions I paste here the link: https://dev.mysql.com/doc/connector-...on-source.html
