![]() For example, when you run the command, # info grep Many of the instruction manuals, or info pages, bundled with Unix-like operating systems are compressed to save space. ![]() Now I'll dismiss the compression format more commonly associated with Windows operating systems for a moment and doff my cap at files compressed with gzip. Using that file, I'll start with a simple grep example that searches for a pattern within a file: # grep one filenameįigure 5: Zgrep is clever enough to delve inside a ZIP file. To get moving in the right direction, I'll consider a text file with five lines of words ( Figure 1, top). First, I want to get my hands dirty with a reminder of some of the basics. ![]() The stalwart that is grep comes to a command prompt near you in a few forms, but I'll come to that a little later. With grep you can rifle through just one file, all of a directory, the process table, and much more without batting an eyelid. Not Such a Bad PilotĪs most sys admins soon discover, one of the heroes of the Linux command line is the grep command. Therefore, in this article, I will dig into some of the history of grep and attempt to help you improve your readily available knowledge, with the aim of being able to solve problems more efficiently and quickly. When I typed history at the prompt, lo and behold, that old favorite grep stood out as something I use continually throughout my working day. To increase my efficiency in creating command lines and scripts, I made a conscious decision to start again and effectively go back to basics with some of the core shell commands that is, I wanted a timely way to improve my understanding of a few key packages so that I wasn't always looking up a parameter or switch and, thus, speed up my ability to automate tasks. In the end, I concluded that clever little command lines were the way forward, and in most cases, these could translate into clever little shell scripts. When I recently spent some time away from the computer monitor, I had a chance to consider what I could use to help automate tasks and to think about the procedures that I face routinely. ![]() I have had many a moment in which I lucidly caught myself thinking: "Not this task again! I really need to speed this process up." By simply automating a procedure or ultimately deprecating and condemning it as redundant, I could save a lot of time in the long run. She said together in “The Secret Garden,” cast and audience travel through a story that’s very much about sorrow and grief but comes to a place of healing and redemption.We are all creatures of habit in varying degrees, and I frequently find myself settling into various routines in my job as a sys admin. Haynie said “The Secret Garden” has a relatively small cast for a musical but features four performers new to the MLT stage. I also think it’s also magical for young people to see her, someone their size and age, and realize what they might do themselves. It’s wonderful seeing someone her age mature on stage. She does a marvelous job and our audiences will remember her playing Annie and being just magnetic on stage. Then there’s Abigail Watson, who plays young Mary. “DeAnna is a voice major at Wesleyan College. “That includes DeAnna Laree, who plays the young adult female lead in the play, Lilly, the ghost who helps Mary find her way into the secret garden,” she said. ![]() “There’s tremendously beautiful music that’s quite demanding of singers, but we have some great singers and phenomenal soloists.” “I think it features powerful, emotional acting and a beautiful, lush score,” Haynie said. ![]()
