使用变量从bash运行IDL程序

发布时间：2020-12-16 01:34:57 所属栏目：安全来源：网络整理

导读：我在IDL中编写了一个程序,用于根据命令行参数生成散点图.我可以直接在终端中成功调用程序,如下所示： idl -e “scatterplot_1_2d_file.pro” $infile $outfile $title $xtitle $ytitle $xmin $xmax $ymin $ymax $timescale 其中$*引用了一些输入的字符串文字

我在IDL中编写了一个程序,用于根据命令行参数生成散点图.我可以直接在终端中成功调用程序,如下所示：

idl -e “scatterplot_1_2d_file.pro” $infile $outfile $title $xtitle $ytitle $xmin $xmax $ymin $ymax $timescale

其中$*引用了一些输入的字符串文字.问题是,我以为我只能输入那一行,将变量名代替文字,放入bash脚本,并生成一百万个散点图我在休息时.不幸的是,如果我这样做,我得到错误：

idl: -e option cannot be specified with batch files

所以我的下一次尝试是尝试将这些命令写入我随后运行的IDL批处理文件.

这种尝试看起来像这样：

#!/bin/bash

indir=/path/to/indir/
outdir=/path/to/outdir/

files=`ls $indir`
batchfile=/path/to/tempbatchfile.pro

echo .r "/path/to/scatterplot_1_2d_file.pro" >> $batchfile

for file in $files
  do
  name=${file%.*}
  echo scatterplot_1_2d_file $indir$name.txt $outdir$name.jpg $name "Gauge Precipitation (mm)" "NMQ Precipitation (mm)" "*" "*" "*" "*" 2 >> $batchfile
done #done file                                                                                                                                                                                                

echo exit >> $batchfile

idl <<EOF                                                                                                                                                                                                      
@/path/to/scatterplot_1_2d_file                                                                                                                                                                  
EOF                                                                                                                                                                                                            

rm $batchfile

我不知道脚本生成的大部分错误是否相关,所以我只是发布开始,如果需要,我会稍后发布其余的：

我不知道我是不是只想做一些无法做到的事情,但它并不喜欢它.有什么建议？

有两种方法可以解决这个问题：使用COMMAND_LINE_ARGS或构建有效的IDL例程调用.此例程使用两者：

pro test,other_args
  compile_opt strictarr

  args = command_line_args(count=nargs)

  help,nargs
  if (nargs gt 0L) then print,args

  help,other_args
  if (n_elements(other_args) gt 0L) then print,other_args
end

使用以下两种方法之一从命令行调用它：

Desktop$idl -e "test" -args $MODE
IDL Version 8.2,Mac OS X (darwin x86_64 m64). (c) 2012,Exelis Visual Information Solutions,Inc.

% Compiled module: TEST.
NARGS           LONG      =            1
test
OTHER_ARGS      UNDEFINED = <Undefined>
Desktop$idl -e "test,'$MODE'"
IDL Version 8.2,Inc.
Installation number: 216855.
Licensed for use by: Tech-X Corporation

% Compiled module: TEST.
NARGS           LONG      =            0
OTHER_ARGS      STRING    = 'test'
test
