Display File Content with Colors and Line Number Alternative to cat Ubuntu

Sometimes you may want to quickly display the contents of a file directly on the command line with the `cat` command. And sometimes the contents of that file is the source code of a program.

If you want to display the source code markup with colors and line numbers, then this trick is what you are looking for.

What you need to do first is install Pygments, a python syntax highlighter.

sudo apt-get install python-pygments python3-pygments

After installing pygments, you can now view source code with colored markups. just run the ff:

pygmentize testfile.rb

Now for the line numbers, you will have to pipe the `nl` command

pygmentize testfile.rb | nl --body-numbering=a

The option

--body-numbering

means it will accept a style for line numbering and it is any of the ff:

a - number all lines
t - number only nonempty lines
n - number no lines

I used a so that everything will be numbered including empty lines.

We can actually add nl options in bash alias so that we do not have to type it everytime.

alias nl=nl --body-number=a

While at it, lets also shorten the pygmentize command.

alias ccat=pygmentize

Now the source code syntax will be highlighted everytime we ran this command:

ccat testfile.rb | nl

Display PDF in assets folder inside APK

The example "Display PDF using PdfRenderer" show how to display PDF stored in sdcard, this example show how to display PDF stored in assets inside APK.

Then you have to edit aaptOptions in build.gradle (Module: app), not to compass "pdf" file.


 aaptOptions {
 noCompress "pdf"
 }

Layout file, refer to the example "Create PDF using PdfDocument".

 try {
 openPDF();
 } catch (IOException e) {
 e.printStackTrace();
 Toast.makeText(this,

 Toast.LENGTH_LONG).show();
 }
 }

 private void openPDF() throws IOException {

 //open file in assets

 AssetManager assetManager = getAssets();

 //open file from sdcard
 /*
 String targetPdf = "/sdcard/test.pdf";
 File file = new File(targetPdf);

 ParcelFileDescriptor fileDescriptor = null;
 fileDescriptor = ParcelFileDescriptor.open(
 file, ParcelFileDescriptor.MODE_READ_ONLY);
 */

 //min. API Level 21
 PdfRenderer pdfRenderer = null;
 pdfRenderer = new PdfRenderer(fileDescriptor);

 final int pageCount = pdfRenderer.getPageCount();
 Toast.makeText(this,
 "pageCount = " + pageCount,
 Toast.LENGTH_LONG).show();

 //Display page 0
 PdfRenderer.Page rendererPage = pdfRenderer.openPage(1);
 int rendererPageWidth = rendererPage.getWidth();
 int rendererPageHeight = rendererPage.getHeight();

 rendererPageWidth,
 rendererPageHeight,
 Bitmap.Config.ARGB_8888);
 rendererPage.render(bitmap, null, null,
 PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);

 pdfView.setImageBitmap(bitmap);
 rendererPage.close();

 pdfRenderer.close();

 assetFileDescriptor.close();
 }
}

Display All The Text Files From A Directory Using C

DESCRIPTION:

This program get the directory path from the user and display all the text files available in the directory.

We should add dirent.h header file to accomplish this program.

PROGRAM:

#include <string.h>
#include <dirent.h>
#include <string.h>
const char *only_txt (const char *);

int main (int argc, char *argv[])
{
    DIR *directory;
    struct dirent *file;     
    directory = opendir (argv[1]);
    int directory_length = strlen(argv[1]);
    if (directory != NULL){
        while (file = readdir (directory)){
            if( !strcmp((only_txt (file->d_name)), ".txt") )
                      puts (file->d_name);
        }
        (void) closedir (directory);
      }
      else
        perror ("Not able to open the directory ");
    return 0;
}

/**load only .txt file**/

const char *only_txt (const char *filespec) 
{
    char *file = strrchr (filespec, .);
        if (file == NULL)
            file = "";
    return file;
}

COMPILE:

    gcc -o out scan.c

RUN:

Pass the directory name with the path as argument to the program

./out /home/sujin/directory

OUTPUT:

test.txt

README.txt

Display amount of free and used memory in the system In Ubuntu

By using free you can display amount of free and used memory in the system.
Free displays the total amount of free and used physical and swap memory in the system, as well as the buffers used by the kernel. The shared memory
column should be ignored; it is obsolete.

Example:

free -m

Will display something like this:

 total used free shared buffers cached
Mem: 244 240 3 0 15 82
-/+ buffers/cache: 143 101
Swap: 715 107 608

Usage:

free [-b | -k | -m | -g] [-o] [-s delay ] [-t] [-V]

Options:

The -b switch displays the amount of memory in bytes; the -k switch
(set by default)
displays it in kilobytes; the -m switch displays it in megabytes;
the -g switch displays it in gigabytes.

The -t switch displays a line containing the totals.

The -o switch disables the display of a "buffer adjusted" line. If the
-o option is not
specified, free subtracts buffer memory from the used memory and
adds it to the free memory reported.

The -s switch activates continuous polling delay seconds apart. You may
actually specify
any floating point number for delay, usleep(3) is used for
microsecond resolution delay times.

The -V displays version information.

Display PDF using PdfRenderer

The class android.graphics.pdf.PdfRenderer enables rendering a PDF document. This example show how to:

MainActivity.java

package com.blogspot.android_er.androidpdf;

import android.graphics.Bitmap;
import android.graphics.pdf.PdfRenderer;
import android.os.Bundle;
import android.os.ParcelFileDescriptor;
import android.support.v7.app.AppCompatActivity;
import android.widget.ImageView;
import android.widget.Toast;

import java.io.File;
import java.io.IOException;

public class MainActivity extends AppCompatActivity {

 String targetPdf = "/sdcard/MagPi54.pdf";

 ImageView pdfView;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

 pdfView = (ImageView)findViewById(R.id.pdfview);

 try {
 openPDF();
 } catch (IOException e) {
 e.printStackTrace();
 Toast.makeText(this,
 "Something Wrong: " + e.toString(),
 Toast.LENGTH_LONG).show();
 }
 }

 private void openPDF() throws IOException {
 File file = new File(targetPdf);

 ParcelFileDescriptor fileDescriptor = null;
 fileDescriptor = ParcelFileDescriptor.open(
 file, ParcelFileDescriptor.MODE_READ_ONLY);

 //min. API Level 21
 PdfRenderer pdfRenderer = null;
 pdfRenderer = new PdfRenderer(fileDescriptor);

 final int pageCount = pdfRenderer.getPageCount();
 Toast.makeText(this,
 "pageCount = " + pageCount,
 Toast.LENGTH_LONG).show();

 //Display page 0
 PdfRenderer.Page rendererPage = pdfRenderer.openPage(0);
 int rendererPageWidth = rendererPage.getWidth();
 int rendererPageHeight = rendererPage.getHeight();
 Bitmap bitmap = Bitmap.createBitmap(
 rendererPageWidth,
 rendererPageHeight,
 Bitmap.Config.ARGB_8888);
 rendererPage.render(bitmap, null, null,
 PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);

 pdfView.setImageBitmap(bitmap);
 rendererPage.close();

 pdfRenderer.close();
 fileDescriptor.close();
 }
}

layout/activity_main.xml, add a ImageView to display the PDF:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
 
 
 android_id="@+id/activity_main"
 android_layout_width="match_parent"
 android_layout_height="match_parent"
 android_paddingBottom="@dimen/activity_vertical_margin"
 android_paddingLeft="@dimen/activity_horizontal_margin"
 android_paddingRight="@dimen/activity_horizontal_margin"
 android_paddingTop="@dimen/activity_vertical_margin"
 android_orientation="vertical"
 tools_context="com.blogspot.android_er.androidpdf.MainActivity">

 <TextView
 android_layout_width="wrap_content"
 android_layout_height="wrap_content"
 android_layout_margin="20dp"
 android_layout_gravity="center_horizontal"
 android_autoLink="web"
 android_text="http://android-er.blogspot.com/"
 android_textStyle="bold"/>

 <ImageView
 android_id="@+id/pdfview"
 android_layout_width="match_parent"
 android_layout_height="match_parent" />
</LinearLayout>

uses-permission of "android.permission.READ_EXTERNAL_STORAGE" is needed in AndroidManifest.xml to read file from sdcard.

<?xml version="1.0" encoding="utf-8"?>
<manifest 
 package="com.blogspot.android_er.androidpdf">

 <application
 android_allowBackup="true"
 android_icon="@mipmap/ic_launcher"
 android_label="@string/app_name"
 android_supportsRtl="true"
 android_theme="@style/AppTheme">
 <activity android_name=".MainActivity">
 <intent-filter>
 <action android_name="android.intent.action.MAIN" />

 <category android_name="android.intent.category.LAUNCHER" />
 </intent-filter>
 </activity>
 </application>
 <uses-permission android_name="android.permission.READ_EXTERNAL_STORAGE"/>

</manifest>
