A bit about the stuff I've done

Cheetsheet

This is my "cheetsheet" or reference card.
I'll update this post as and when but really its just a place to store the stuff I always forget how to do or the exact syntax involved.

Bash:


For:

for f in dir/file*  do    echo "Processing $f"    # do something on $f  done
for i in {0..10..2}    do echo "Welcome $i times"  done

Ascii dec/hex/binary table

Key:

decimal numbers (base 10) hexadecimal numbers (base 16) ascii character or control code binary digits (base 2). The top table has binary 0 as the first digit, the bottom table has binary 1
The binary numbers across the top are the next most significant digits
The binary numbers down the left side are the final 4 digits
so for example: 182 (B6) has a 1 for the first digit as its in the bottom table, Next look to the top of the column to get 011
and finally look at the row to get 0110
So the entire sequence is 10110110
