Question

对于AIX 7.X，我的gnuplot脚本具有以下几行：

set terminal png truecolor size 1950, 650  background rgb "#eff1f0" 
set output "/xxx/xxxx/xxx/xxx/xxx.png"
set datafile separator ';'

set size ratio 0.2
set bmargin at screen 0.2
unset key
set datafile separator ";"
set ylabel " MB BLOCK " font ",10" offset -1,0
set xlabel font ",10"
set xtics rotate by 45  offset -0.8,-9,-1.8


plot "xx/xx/file.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \ 
plot "xx/xx/file.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \ 
plot "xx/xx/file.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \

plot "xx/xx/file.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5

除了第一行外，我想删除所有行的模式“ plot” ...使用我的Linux，我可以这样做：

sed '0,/plot/! s/plot//g' myfile.txt

结果是：

set terminal png truecolor size 1950, 650  background rgb "#eff1f0" 
set output "/var/IBMtools/www/tim/used.png"
set datafile separator ';'

set size ratio 0.2
set bmargin at screen 0.2
unset key
set datafile separator ";"
set ylabel " MB BLOCK " font ",10" offset -1,0
set xlabel font ",10"
set xtics rotate by 45  offset -0.8,-9,-1.8

 "xx/xx/file.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5

但是此命令不适用于AIX。错误是sed: 0602-403 0,/plot/! s/plot//g is not a recognized function.

请，你能告诉我怎么做吗？

如果您可以使用awk解决方案，请尝试以下方法。

awk '/plot/ && ++count==1{print;next} !/plot/' Input_file

说明： 添加上述代码的说明。

awk '                         ##Starting awk program from here.
/plot/ && ++count==1{         ##Checking condition if string plot is present and variable count value is 1 then do following.
  print                       ##Printing the current line.
  next                        ##next will skip all further statements from here.
}                             ##Closing BLOCK for above condition.
!/plot/                       ##Checking condition if string plot is NOT present then do print of that line.
' Input_file                  ##Mentioning Input_file name here.

注意： ：如果要将输出保存到Input_file本身，请在上述代码后附加> temp && mv temp Input_file。

如果绘图不在文件的第一行，则可以执行以下操作：

 def convertJsonToListModel[T](json: JsValue)(implicit reads: Reads[T]): List[T] = {
      val conversionResult: JsResult[List[T]] = json.validate[List[T]]
      conversionResult match {
        case s: JsSuccess[List[T]] => s.get
        case e: JsError => e.get
      }
 }

如果它可以出现在第一行，那么我只能循环播放它：

sed '1,/plot/!s/plot//'

AIX：sed命令删除除第一行以外的所有行的模式
