bash $? style - looking for something organized

Saw a really clean style of error checking but trying to get the syntax straight and made it kind of self documenting? (something like this - just two lines he did it and looked very organized" # below is the statement and checked somelinuxcommand $$ x=$? if x!=0 echo "error with somelinuxcommand$x" fi anotherlinuxcommand $$ x=$? if x!=0 echo "error with anotherlinuxcommand $x" fi somebluecommand $$ x=$? if x!=0 echo "error with somebluecommand $x" fi redredredred $$ x=$? if x!=0 echo "error with redredredred $x" fi SINCERELY WOULD BE NICE TO MEET YOU PLEASE ------------------------------------------------------------------------------------------------------------------------------------ There is hope you can give your “best” price; unemployed, and have cancer with bills backing up. $12 ok? My funds are low but will pay quick and leave 5 stars. Please give your best possible for your bid ? (something reasonable?) Please note there is hope we can mutually complete this task; we can leave each other nice comments and 5 stars for each? Look at feedback on my profile, feedback I left for many others. Here is the project: ANY THOUGHTS ? Please note project is due in two hours as this projects deadline, as this is needed if we can get some done - then we can talk about next steps and 5 stars and another job also. If this is a good one and we are "successful"; would need a couple others setup, but will handle one at a time? Can you do this for something reasonable in a couple hours? thoughts ?
