i guess i might get in 4th year only😂
As per one of my friend in RH, it is Remote Job, FYI Red hat has offices in Delhi, BLR, Mumbai, Pune and Kolkata as well. if you good in coding and Linux you will definitely crack the job.
@@amitjha35 but devops is for automation right?
the devops zero to hero playlist enough?
what i mean is things like shell,terraform,AWS are only required
or i have to create applications also?
Bro any openings for Devops, currently I am working as network engineer@@sudo-thinkit
is this the combination of your shell scripting videos?
Yes
HI Abhi, what if the log file to capture certain error description timely and redirect to an output to a file, where file name to be in date format on each day and log time and it has to be taken twice a day and the second time log file to be appended to the first minute of the day logs.
Instead of curl, curlie is much better 😊

Great
code provided in video(02:34:14) didn't work on my ubuntu system. I edited it as follows to make it work:
for i in {1..100}; do
if ( [ $(expr $i % 3) -eq 0 ] || [ $(expr $i % 5) -eq 0 ] ) && [ $(expr $i % 15) -ne 0 ]; then
echo $i
fi
done
till now no reply 🤣🤣🤣🤣🤣🤣🤣
Hello Abhishek is this for mlops.
Hi Abhishek
Can you do playlist on DevSecOps
Abhishek i spent 60k on learning devops+aws but i don't get any learning from them.. i saw your videos and they are really helpful and and from 1 week i start learning from your video's only..
Can someone become devops engineer in 3 months from your videos?
100% bro --by the help of his videos I got more than 110% hike
Unfortunetly a big NO, bcz devops is very tricky it will take atleast 6 month if you have good understanding of cloud ,networking ,linux and finaly scripting last but not least a besic of python
if you have above skill then yeah you will probably become master in devops
Hi Abhishek .. i have 1 doubt ... for example we have running multiple process .. like java and aws then how to find both process id in single command .. i tried like ps -ef | grep 'java|aws' but its not showing out for java and aws ..its giving output in single line.. plz guide thanks
Hi Abhishek .. waiting for ur response ..plz.. thanks
@@akhileshmu007 You need to add -E flag
ps -ef | grep -E " aws|java"
Please make videos of zero to hero on MLOPS & ALOP

@@AbhishekVeeramalla sure Abhishek will do that
Can you make a video for powershell also for the beginner?
Is powershell needed, when we connect to server using Linux?
nano is even better and simpler to use rather than vi or vim....isn't it?
Instead of grep, ripgrep is much better 😊
Hey Abhishek Sir …. Is Your AWS playlist help me to Clear AWS Cloud Practitioner certification pls anna reply 🙏🏻🙏🏻🙏🏻🙏🏻🥲🥲🥲🥲
Instead if find, fzf is much better 😊
hi 5 aug vala session record karna sir..bhale hi topmate pe becho..please sir
What you told are basics of shell script
what does the ^C mean after each command ?
When u want to terminate anything u have to use control C. So he is using control C to terminate that line bcoz if he type enter to move to next line that invalid line gives this is not a command like that error so he is terminating every line with ctrl C which is ^C. Terminating means stopping the execution.
is it enough for devops
Instead of cat, bat is much better 😊
Is this enough to become pro in shell scripting ?
no
Instead top, htop is much better 😊
First like first comment ❤️
what editor are you using?
Camtasia

This is not hero ending bro
If, and for loop. There nothing new you've teached to be honest. You could have shown us how this if and for loop in used in real time kind of scenario.
Obviously bcs we will not use to print 1.to 100 number or lacks number. In shell scripting we need real time scenario used in
Hello sir Good Afternoon sir ek video ROOT Volume EBS ko decrease kase kare ise par laker aao
sir mena ubuntu ec2 par volume Decrease kane ka liya 10-12 Time Try kar Liya But ec2 machine start hi nhi hoti
You cannot decrease ebs root volume of a ec2 instance. You will have to reboot the server or make a new one I think.
