We are a team of young blood. Some of our Payilagam team mates are Childhood friends, few college mates and few other as Colleagues in Professional life and ended as friends. One common thing about the Payilagam team is we have around Five Years of experience in the Software field. When we came out of our college campus the entire world was new to us. Though we were alumni of various leading government and private engineering colleges, we experienced difficult situations and the road to reach this position had lot of hurdles. Each of us realized that there is a huge gap between the 10+2+4 education system and the Jobs field what we want to be in. During our initial days of job hunt, we found many software training centers with fake promises of placement and career. Some of our friends believed those fake promises, joined there with dreams and hopes but all went in vain. None of the claims of these institutes were true, are true and neither will be. These so called “Best Software Training Institutes” captivate the students not for the welfare of the students but for their own profit margins. These taught us strong lesson not to believe these software training institutes in Chennai. All these experience fed us thought for starting a software training institute in Chennai and in turn saw the seed ‘Payilagam’. We don’t endorse ‘Payilagam’ as the best, We don’t endorse ‘Payilagam’ as No 1 institute in Chennai, But we endorse ‘Payilagam’ with its moral. We started Payilagam Software Training Institute with the moral vision to nurture professionals of high academic caliber and perfect character, nurture with a strong motivation and commitment to serve humanity. We aim at training our trainees to become not only skilled professionals but also excellent human beings to influence the quality of life of people around. There were no one to guide us when we were about to start our career, But Payilagam is there for you.

Labs:
1. Introduction to the lab environment and using the shell
2. Using, navigating, and searching man pages. Using the Linux info command.
3. Explore different file types: files, directories, devices, and links. Use basic commands to
navigate and explore files and directories (cd, 1s, pwd, cat, and date).
4. Explore top-level directories. Use shortcut names to navigate and view directories, Use
the file and od commands to view file and directory details. Use the 1s -1 command to view
file attributes, Use the cd command with relative and absolute pathnames.
5. Use the touch command to create files and modify timestamps. Use the chon command to
change file ownership. Use the 1n command to create a link to a file.
6. Use the chmod command to modify file permissions. Use the umask command to set the
default permissions.
7. Copy, move, and remove files. Use tar to archive files. Use gzip to compress files.
8. Perform basic editing and navigation in vi. Operate effectively in both command and
insert modes.
9. Explore processes using the ps, pstree, and pgrep commands.
10. Perform globbing with different commands. Quote special characters in the shell. Use
command-line shortcuts, such as file completion, command completion, command history,
and repeating commands, to more efficiently work in the UNIX shell.
11. Modify your UNIX profile, including your unmask, setting your path, setting your own
variables, setting aliases, setting options, and defining functions. Edit the .forward file.

12. Create a shell script using a text editor, such as vi. Include comments, white space, and
the shbang line. Include the echo and read commands in the script. Give yourself execution
permission for the script. Run the script to make sure that it works. Address any problems
that prevent the script from running correctly.
13. Redirect the output of standard out and standard error to files. Implement noclobber to
prevent file destruction. Use piping to send the standard out of one command to the
standard in of another command.
14. Use the four methods for performing conditional testing (|| and &&, test command, [ ],
and [[ ]]) to write conditional statements into a script. Use if, then, if and elif statements.
15. Introduce various types of loops (for, while, until) into your script. Use the seq
command. Implement abnormal loop termination.
16. Use find and locate to find files based on partial information. Use the du and df
commands to monitor disk usage.
17. Use various regular expressions to force a command to display only a specific portion of
its full output.
18. Use grep and egrep to find regular expressions within a file. Use wc to return word
count. Sort files. Use sed and awk to manipulate the data within a file.
