utility script-2

This is a shell script that automates the compilation of single c/c++ source file and executes this.

<br /><br />#!/bin/bash<br />#Developed by : lipun4u@gmail.com<br /><br />file_name=$1<br />c_extension=".c"<br />cpp_extension=".cpp"<br />ip_file_name="$file_name$c_extension"<br />i=0<br /><br />if [ $# -ne 1 ]<br />then<br /> echo "Usage: `basename $0` <source-file>"<br /> echo "Source file should be without extension"<br /> echo "e.g :-`basename $0` test" <br /> exit 1<br />fi<br /> <br />if [ -f $ip_file_name ]<br />then<br /> echo "compiling c-source file $file_name ....."<br /> gcc -o $file_name $ip_file_name -lpthread<br /> if [ $? -eq 0 ]<br /> then <br /> i=1<br /> fi<br />else<br /> ip_file_name="$file_name$cpp_extension"<br /> if [ -f $ip_file_name ]<br /> then<br /> echo "compiling c++-source file $file_name ....."<br /> g++ -o $file_name $ip_file_name -lpthread<br /> if [ $? -eq 0 ]<br /> then<br /> i=1<br /> fi<br /> else<br /> echo "compilation failed"<br /> exit 1<br /> fi<br />fi<br /><br />if [ $i -eq 1 ]<br />then<br /> echo "Output file name : $file_name"<br /> echo "Executing......"<br /> echo<br /> ./$file_name<br /> exit_status=$?<br /> if [ $exit_status -ne 0 ]<br /> then<br /> echo "Program execution failed with exit status $exit_status"<br /> exit 1<br /> fi<br /> echo<br /> echo "Program executed successful"<br />fi<br /><br />

utility script-1

This is an utility script that makes a file executable and opens in vi editor.

<br /><br />#!/bin/bash<br />#Developed by : lipun4u@gmail.com<br /><br /><br />if [ $# -ne 1 ] <br />then<br /> echo "Usage: `basename $0` <filename>"<br /> exit 1<br />fi<br /><br />touch $1<br />chmod u+x $1<br />vi $1<br /><br />

clipboard logger

This code snippet logs all clipboard text in a log file...

<br />#include <windows.h><br />#include <stdio.h><br />#include <string.h><br />#include <stdlib.h><br /><br />using namespace std;<br /><br />void myfree();<br />FILE *fp;<br />char *p;<br />HANDLE clip;<br /><br />int main()<br />{<br /> HANDLE clip;<br /> p=(char*)malloc(1);<br /> *p='\0';<br /> fp= fopen("log.txt", "a");<br /> atexit(myfree);<br /> while(true)<br /> {<br /> if (OpenClipboard(NULL))<br /> {<br /> clip = GetClipboardData(CF_TEXT);<br /> if(strcmp(p,(char*)clip)!=0)<br /> {<br /> free(p);<br /> p = (char*)malloc(strlen((char*)clip)+1);<br /> strcpy(p,(char*)clip);<br /> fprintf(fp,"%s",p);<br /> }<br /> CloseClipboard();<br /> }<br /> Sleep(500);<br /> } <br />}<br /><br />void myfree()<br />{<br /> free(p);<br /> if(fp!=NULL)<br /> fclose(fp);<br /> free(clip);<br />}<br />

This is well tested in Dev C++.
