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.

Great playlist sir... sir DevOps ke liye itni shell scripting aani sufficient hogi ya aur bhi padhna hoga, agar aur bhi padhna ho toh please topics suggest kr dijiye...
aur lagega.. thoda aur advanced
Sir my cronjob doesn't work
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.
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?
