Maybe someother cool things about it. Thx for the information in advance!! History feature in Unix. In HP-UX, for executing the previous commands, i use the arrow keys. But on sun solaris this is not working. Can anyone explain how to use history feature effectively in sun solaris os?

Thanks 4 Replies. How to track the modification history on file in unix. How do we track the modification history on a file in UNIX.

IS there any command or any script that we could run. Many Thanks 5 Replies. Because Bash ignores lines that begin with a space by default, just include a space at the start of the line, as follows:.

The reason this trick works is contained within the. It also contains some values that control the behavior of the history command. You would follow this structure to add a line to your. To do so, you just add a line like the following to your. This prevents the timestamp from butting up to the commands in the command list. Now, when you run the history command, you see date- and timestamps.

Note that any commands that were in the history list before you added the timestamps will be timestamped with the date and time of the first command that receives a timestamp. In this example shown below, this was command The other tokens you can use are:. This is possible because the time for each command is stored as the number of seconds from the Unix epoch.

You can also use the history command to audit. Just as you can in life, on Linux, you can use the history command to relive the good times and learn from the bad. Use Google Fonts in Word.

Source: A brief look at the early history Unix was born in not , and the account of its development makes a little-known and perhaps instructive story. This paper presents a technical and social history of the evolution of the system. Resources : Dennis Ritchie's home page Ken Thompson's home page. Universities, research institutes, government bodies and computer companies all began using the powerful UNIX system to develop many of the technologies which today are part of a UNIX system.

Computer aided design, manufacturing control systems, laboratory simulations, even the Internet itself, all began life with and because of UNIX systems. Most telephone calls could not be made, electronic commerce would grind to a halt and there would have never been "Jurassic Park"!

By the late 's, a ripple effect had come into play. By now the under- and post-graduate students whose lab work had pioneered these new applications of technology were attaining management and decision-making positions inside the computer system suppliers and among its customers.

And they wanted to continue using UNIX systems. Soon all the large vendors, and many smaller ones, were marketing their own, diverging, versions of the UNIX system optimized for their own computer architectures and boasting many different strengths and features. Customers found that, although UNIX systems were available everywhere, they seldom were able to interwork or co-exist without significant investment of time and effort to make them work effectively. The trade mark UNIX was ubiquitous, but it was applied to a multitude of different, incompatible products.

In the early 's, the market for UNIX systems had grown enough to be noticed by industry analysts and researchers. Throughout the early and mid's, the debate about the strengths and weaknesses of UNIX systems raged, often fuelled by the utterances of the vendors themselves who sought to protect their profitable proprietary system sales by talking UNIX systems down. And, in an effort to further differentiate their competing UNIX system products, they kept developing and adding features of their own.

In , another factor brought added attention to UNIX systems. A group of vendors concerned about the continuing encroachment into their markets and control of system interfaces by the larger companies, developed the concept of "open systems. Open systems were those that would meet agreed specifications or standards.
