怎么通過(guò)FOR循環(huán)簡(jiǎn)化這個(gè)腳本呢？

腳本如下
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
怎么通過(guò)FOR簡(jiǎn)化他們呢？謝謝大神們了！

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

我的代碼是這樣的，剛才發(fā)的有點(diǎn)問(wèn)題
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"

         set  pibyt3 = $pibyt"MB"
endif

pibyt1，pibyt2，pibyt3之前都有賦值的！

csh的for命令語(yǔ)法是：

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