Learning and challenging days

Today I made a few bash scripts which read the data from the file and then process that data in a meaningful way by using Grass software. I have also learnt stuff related to contour by Grass software.

One interesting thing happened today

When I have given my bash script to Amarjeet and he runs my bash script as sh myscript.sh and it gave an error “Unexcepted token error [[” but on my laptop was working fine. On my laptop I run my bash script as ./myscript.sh and then after some time I found the answer that why script gives an error on Amarjeet’s laptop. Actually, he runs my script in sh shell whereas I have written my script according to the bash shell and then I told to Amarjeet to run my bash script as bash myscript.sh or as ./myscript.sh.
