Dear all, I am trying to do some operation within a bash script but I am running into problems very early.
Say I want to do the following: ------------- omegaNew=`echo "$omegaNew+$torque*$dt/$momentOfInertia*180/$pi" | bc -l` ----------- I got these outputs: ----- torque= -0.0665625 dt= 0.0012 omegaNew= -.00026392835805117909 torque= 0.48041 dt= 0.000101208 omegaNew= -.00010327107397767696 (standard_in) 1: syntax error torque= 1.14457 dt= 2.39891e-05 omegaNew= ----------- Does this mean that the operation is not carried if the torque is not in the form 0.******? If so, why is that? Another unrelated question: I got this output message, ---------- sed: -e expression #1, char 1: unknown command: `C' --------- even the command did what it was supposed to do (i.e., inserting a line) whould one know how to get rid of this thing? Best regards to all. -- View this message in context: http://old.nabble.com/doing-operations-with-bash-script-tp33447614p33447614.html Sent from the Gnu - Bash mailing list archive at Nabble.com.
