i am trying to assign the following expression to a variable in Unix shell script
and want to use that variable in some other expression. But unable to get the required thing done. Please help with this....
This is the expression which i want to provide as input the variable
date '+%y:%m:%d' | awk -F":" '{printf"20%2d%2d%2d\n",$1,$2,($3-1)}' | sed 's/ /0/g'
like
d = `date '+%y:%m:%d' | awk -F":" '{printf"20%2d%2d%2d\n",$1,$2,($3-1)}' | sed 's/ /0/g'`
That is not a good way to get the previous day. What happens on the 1st of a month?
Variable assignments do not have spaces around the = sign. You need to leave them out.
