I'm on a Centos box, trying to send a UDP packet to port 8125 on localhost. When I run this Python script:
import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.sendto('blah', ("127.0.0.1", 8125))
The data appears where it should on port 8125.
How can the white space character be escaped in printf for the purpose of this script that currently runs in a Cygwin client?
Getting the below error while executing this. Able to run the below commands Individually.
#!/bin/bash
a=$(printf "%d\n" 0x01E);
b=$(printf "%d\n" 0x01A);
echo $a
echo $b
c=`expr $a - $b`
echo $c
syntax error at line 2: `a=$' unexpected

I have a little problem with a small script.
Hi people,
I am new to shell scripting, My problem is i have the output of a shell command in one file,and an output of another command in another file, what i want is, I want to append the output of the second command at a particular location of the first file recursively.
Ex:(OUTPUT OF Ist COMMAND)File 1 -->
Code:
-------------------blah blah blah some link(/blah/blah/blah) blah blah --
I have a rather weird issue.
I am some new to the programming world but starting to get hang of it.
My question is,what shell should I use bash or sh (Ubuntu uses dash for sh)
Is the one faster, users more memory etc?
Example scripts
Code:
#1
for I in {1..10}; do echo $I; done
#2
for I in 1 2 3 4 5 6 7 8 9 10; do echo $I; done
#3
for I in $(seq 1 10); do echo $I; done
#4
for ((I=1; I <= 10 ; I++)
