Question

我正在尝试根据我在某些页面编号上找到的字符串将tempfile.pdf与pdftk分开。那些pagenumbers在tempfile中。

n=0
prefix1="startpoint"
prefix2="stoppoint"
while read p; do
  echo $p > temp
  `cat temp` = prefix1$n
  echo $((p-1)) > temp
  `cat temp` = prefix2$n
  n=$((n+1));
done < tempfile

pdftk tempfile.pdf cat $startpoint0-$stoppoint1 output $1/01-0.pdf
pdftk tempfile.pdf cat $startpoint1-$stoppoint2 output $1/02-0.pdf
pdftk tempfile.pdf cat $startpoint2-end output $1/03-0.pdf

出于某种原因，我得到这样的错误：

/usr/local/bin/skapa_digital_akt: rad 16: 1: kommandot finns inte
/usr/local/bin/skapa_digital_akt: rad 18: 0: kommandot finns inte
/usr/local/bin/skapa_digital_akt: rad 16: 6: kommandot finns inte

显然，变量startpoint / stoppoint设置错误。有人可以帮帮我吗？

非常感谢！

Answer 1

什么是

`cat temp` = prefix1$n

应该这样做？您应该知道：它从temp读取命令行并执行它。

如果temp包含一行1（而n为== 0），则执行的命令将为：

1 = prefix10

您可以通过在脚本上插入set -x或使用sh -x yourscript.sh

调用脚本来帮助自己调试脚本

这有效：

n=0
while read p; do
  echo $p > tempA$n
  echo $((p-1)) > tempB$n
  n=$((n+1));
done < tempfile

startpoint0=$(cat tempA0)
stoppoint1=$(cat tempB1)
startpoint1=$(cat tempA1)
stoppoint2=$(cat tempB2)
startpoint2=$(cat tempA2)


pdftk tempfile.pdf cat $startpoint0-$stoppoint1 output $1/01-0.pdf
pdftk tempfile.pdf cat $startpoint1-$stoppoint2 output $1/02-0.pdf
pdftk tempfile.pdf cat $startpoint2-end output $1/03-0.pdf

这些变量在这里我做错了什么？
