问如何将命令行上的*.mod文件转换为*.mod文件？

EN

#!/bin/bash
# glp-convert to=lp *.mps
# see also [LPsolve doc on file formats](http://lpsolve.sourceforge.net/5.5/formulate.htm)
# note that glpk .mod is gmpl, not ampl

to=lp

help() {
    cat <<!
--------------------------------------------------------------------------------
glp-convert  [to=glp / lp / mps / freemps]  file*.glp / file*.lp / file*.mod / file*.mps
    converts e.g. file*.mod to file*.lp, gmpl to cplex
    default: to=lp, cplex format
--------------------------------------------------------------------------------
!
    exit
}

case $1 in
to=* )
    export "$1"
    shift
esac

[[ -f $1 ]] ||
    help

glpread() {  # .mod -> --model etc.
    case ${1%.gz} in
    *.glp ) echo --glp ;;
    *.lp )  echo --lp ;;  # cplex
    *.mod ) echo --model ;;  # gmpl math prog lang
    *.mps ) echo --freemps ;;
    * )     exec echo >&2  "? $1 should be .glp .lp .mod or .mps"
    esac
}
