怎么通过FOR循环简化这个脚本呢？

icefishxmg

脚本如下
if ($pibyt1 > 1000000000)  then
        set pibyt1 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt'/1000/1000/1000}'`
        set  pibyt1 = $pibyt"GB"
else
        set pibyt1 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt'/1000/1000}'`
        set  pibyt1 = $pibyt"MB"
endif
if ($pibyt2 > 1000000000)  then
        set pibyt2 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt'/1000/1000/1000}'`
        set  pibyt2 = $pibyt"GB"
else
        set pibyt2 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt'/1000/1000}'`
        set  pibyt2 = $pibyt"MB"
endif

if ($pibyt3 > 1000000000)  then
        set pibyt3 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt'/1000/1000/1000}'`
        set  pibyt3 = $pibyt"GB"
else
        set pibyt3 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt'/1000/1000}'`
        set  pibyt3 = $pibyt"MB"
endif
怎么通过FOR简化他们呢？谢谢大神们了！

Shell_HAT

1. for i in pibyt1 pibyt2 pibyt3; do
   
2.     n=`echo | awk 'BEGIN{printf "%.2f\n", '$pibyt'/1000/1000/1000}'`
   
3.     $i=$n"GB"
   
4. done

我的代码是这样的，刚才发的有点问题
if ($pibyt1 > 1000000000)  then
         set pibyt1 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt1'/1000/1000/1000}'`
         set  pibyt1 = $pibyt"GB"
else
         set pibyt1 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt1'/1000/1000}'`
         set  pibyt1 = $pibyt"MB"
endif
if ($pibyt2 > 1000000000)  then
         set pibyt2 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt2'/1000/1000/1000}'`
         set  pibyt2 = $pibyt"GB"
else
         set pibyt2 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt2'/1000/1000}'`
         set  pibyt2 = $pibyt"MB"
endif

if ($pibyt3 > 1000000000)  then
         set pibyt3 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt3'/1000/1000/1000}'`
         set  pibyt3 = $pibyt"GB"
else
         set pibyt3 = `echo | awk 'BEGIN{printf "%.2f\n", '$pibyt3'/1000/1000}'`
         set  pibyt3 = $pibyt"MB"
endif

pibyt1，pibyt2，pibyt3之前都有赋值的！

4.         eval $i=$x"GB"
   
5.     else
   
6.         x=`echo | awk 'BEGIN{printf "%.2f\n", '$i'/1000/1000}'`
   
7.         eval $i=$x"MB"

for: Command not found.
do: Command not found.
i: Undefined variable.

报错，我这是CSH。。。

csh的for命令语法是：

1. foreach i ( pibyt1 pibyt2 pibyt3 )
   
2.     echo $line
   
3. end
