Highlight wrongly spelt words in unix text file

#usage : scriptname file-name

#this is just the logic, basic validation is only done here

#it can be improved in a better manner.

#Some UNIX flavors have utilities which check the spellings.

while read v_line

do

IFS=" "

 for v_eachword in $v_line

  do

   grep -i `echo $v_eachword | tr -d '[[:punct:]]'` /usr/dict/words >/dev/null

   v_status=$?

   if [ $v_status -eq 0 ]

   then

    echo "$v_eachword \c"

   else

    echo "\033[32m" "$v_eachword \c"

   fi

  echo "\033[0m\c"

This file is creatd to check whether the spellings are correct or wrongg in this file.

It jus checks the spellings not the grammer.

COLORS to your Shell

## Colors to your shell is nothing but colors to the ANSI console. As both are same...

## You tell the console with the codes which mention the #colors..

## I hope below simple commands are self explaining. use #the comment box if you have any doubts..

fg_black="\033[30m"

fg_red="\033[31m"

fg_green="\033[32m"

fg_yellow="\033[33m"

Bully your colleague in UNIX shell

Hi Folks,

Most of the Production Support Engineers will be having their Databases on Unix server.

In those cases most of the time you folks will be using Unix Shells. Then here is a small Unix command to make fun of the colleague who is logged in the same Unix Shell.

write is the unix command which helps to write messages to other person terminal.

syntax:

write username [ttyname]

Examples:

Simple:

banner  server crashed | write joel pts/4

More realistic:

(
 echo "\n\n ------------------------SERVER REBOOT INITIATED-----------------------"
 echo " completed   8% .."
 sleep 2
 echo " completed  24% .."
 sleep 3
 echo " completed  32% .."
 sleep 4
 echo " completed  90% .."
 sleep 2
 echo " completed 100% .."
 echo "\n\n ------------------------SERVER REBOOT COMPLETED-------------------------"
 echo "\nPlease press enter to Exit session..."
 ) | write agtmgt pts/13

Note: Make fun when your colleague is deeply investigation. Yeah, thats real fun folks..

C Program to Remove Comments from the C File

C Program to Remove Comments from the File

Description: This program removes comments starting with '//' i.e., single line comments..

You can edit it to remove '--' comments in SQL by just editing the condition..

#include<stdio.h>
#include<ctype.h>
#include<string.h>
 
#define MAXSIZE 1000
 
main()
{
 
 char c, line[MAXSIZE], oline[MAXSIZE];
 int  i=0, linesize=0, doubleq=0;
 
 FILE *ip ,*op;
 
 clrscr();
 
 
 ip = fopen( "input_ph.txt","r");
 op = fopen( "out_ph.txt","w+");
 
 
  while ( (fgets(line,1000,ip)) != NULL )
   {
    linesize = strlen(line);
 
    for(i=0;i<linesize;i++)
    {
     if ( line[i] == '"' )
     doubleq++;            //for validation of '//' in double quotes
 
     if ( !((line[i] == '/') && (line[i+1] == '/')) || (doubleq%2 == 1) )
     oline[i] = line[i];        //copy char by char to OLINE array
 
     else
     {
     oline[i]='\n';
     oline[i+1]='\0';
 
     doubleq = 0;
     break;     //break out from reading char by char once you find comment i.e., '//'
     }
    }
 
    fputs(oline,op);   //put the line truncated from comments to the output file.
    for(i=0;i<linesize;i++)   //null the arrays
    {
     oline[i]=NULL;
     line[i]=NULL;
    }
    i=0;
  }
 
  fclose(ip);
  fclose(op);
 
 getch();
 return 0;
}

Comments:

The for loop condition should be changed accordingly. This works only in current directory files.
