Shell scripts can act like standard UNIX commands and take arguments from the command line. Arguments are passed from the command line into a shell program using the positional parameters $1 through to $9 . Each parameter corresponds to the position of the argument on the command line. ... For example: cat printps # This script converts ASCII files to PostScript # and sends them to the PostScript printer ps1 # It uses a local utility "a2ps" a2ps $* | lpr -Pps1 printps elm.txt vi.ref msg . ...

... Line radiative transfer in C 18 O, HCO + , and CS lines is considered in a spherically symmetric chemo-dynamical model of a starless core, evolution of which is driven by the ambipolar diffusion. Theoretical line profiles are compared to observational data on the well-known L1544 core, which is one of possible candidates for collapsing protostellar clouds. ... Comparison between modelled and observed spectra suggests that L1544 has flattened structure and is observed at some inclination. ...
