Public private key based login to Unix computer

Public private key based login to Unix computer We know that we can login to a Unix system in several ways. One drawback with username password mode is that there will be requirement to update the password frequently. In such cases, we go for the public key based login.  Required software 1. Putty and puttygen Putty can be downloaded from the download page of  https://www.putty.org/ The downloaded zip contains both putty and puttygen. 2. Winscp This is an optional software which gives a window when dealing with ssh, ftp, sftp connections. This can be downloaded from their official site. https://winscp.net/eng/download.php How it works In the public key based login, we will generate a public key and corresponding private key pair.

PDF files : Merge pdf files into one , extract the pages into new one

 Today, we will take a look into he pdf file management. Many a times we come across situations where  1. We have to extract certain pages of a large pdf file. 2. We have merge several pdf files into a single pdf file. We are covering the basic usage below. We are using Ubuntu Linux for this exercise. Merge several files into a single file 'Pdfunite' is the utility that I will be using today. In my example, I have 3 input files (pdf1.pdf, pdf2.pdf, pdf3.pdf)   Place all the files to be merged in a folder. Use the terminal to navigate to the folder. Execute the command as below: pdfunite is the utility, then we list out all the files in the sequence it has to be added to the resulting file. The last name is the name of the resulting file. The file will be created by the utility. pdfunite pdf1.pdf pdf2.pdf pdf-result.pdf  Now you can see that there is a new large file created using the given input pdf files.  Extract certain pages from a PDF file I am using the 'pdfseparate&#

Linux - How to find all the files that contains a given string

Linux - Find all files that contains a given string. In order to find all the files that contains a given string, we can make use of several commands. One of the simplest option is to use the grep command. grep -R '/path/to/theFiles/' -e 'pattern-to-search' With this execution, grep will go through all the files in the provided location recursively(since we gave -R option) and look for the string-pattern to look for. Then, it will provide a list of files that contains our given string-pattern.
