UNIX for Dummies Questions & Answers

Hi

how can i do this?

1) shell script which writes data and time on to a file if filesystem exceeds 70% of space.

2) make entry to cron table to run a script every 15 mins.

and can anyone expplain or demonstrate the difference between variables used in inside a function and outside a funstion(both variables hav the same name)

ps : this is not homwork.....i am working ..i jus wante dto learn unix and doin some case studies...

Thanks and Regards

1)
man df
man grep
man date
man <whatever shell you use>

That should be all you need... maybe "man sed" and "man awk" too if you're feeling adventurous - there are many ways to solve this.

2)
man cron

Part of the fun of learning UNIX is searching these forums and Google - a voyage of discovery....

People are not going to write your scripts for you. We are all more than willing to help people and answer specific questions - not regurgitate manual pages and write complete solutions.
