About -
TrainWithShubham is the channel created with the idea of bridging up the gap between academical learnings and corporate world. We all know that schools and universities doesn't necessarily prepare us for the corporate world. There's a huge difference between what's going on in the industry and what's being taught to us in schools and colleges.
We are here to prepare you for the world with content based on my industry knowledge & experiences as a developer.

Hello Bhaiya,
maja aagaya aaj bahut kuch seekha.😇
par ek doubt hai ki agar Hour mein hum 4 rakhenge to kya 5 bajne ke baad logs create honge 🤔?
thanks a lot bhai
when we set time for job to execute , we encounter the issue of time zone ,India Standard Time (IST) is 5:30 hours ahead of Coordinated Universal Time (UTC).
please tell us the easy way to understand this ...
Hi shubham ,
Is the cronjob we need to use in k8 & where? Could you explain
@TrainWithShubham can you please make a video on the term used on bash script or in corn like & 2>1 /dev/null.....Something like this...means why it is used, how it is used etc
Which terms, I did not get it.. I'll definitely make videos on it
@@TrainWithShubham He is saying about the usage of 2&>1 in shell script.
Usage :- 2&>1 & to use 2 commands at once at a time.
Else google it.
brother i have used the same code to check disk but in loop where we compare usage with 90 there comes an integer error that it says it cannot compare two different data types what to do ....i have searched and tried a lot of ways but nothing works for me
is video ka part 2 to banta hai bhai please...
Totally boht jald
Ha Shubham bhai cron aur crontab mein kya antar hai kaise kam Karta Hai bilkul samajh mein a raha hai.
badhiyaaa
bhai ye dev loops kab bane the ya banaye the ????
because m 1st vedio se follow krra hu pr dev /loops kha bane ye ni dikhra?
Plz ans
Hi, thankyou for sharing your knowledge
just wanted to ask the difference between the crontab you showed earlier which was in /etc/crontab and the one which we edited through 'crontab -e'
The difference is that the crontab command is the interface provided by the system for users to manipulate their crontabs. The /etc/crontab file is a special case file used to implement a system-wide crontab. /var/spool/cron/crontabs/$USER (or whatever the path happens to be) is an implementation detail.
dear sir how can be set am or pm wise timing set
bhaiya yt-dlp pe upar ek video banao na.
sure
Sir git, GitHub ke videos nhi hai es playlist mai
