用了你這個(gè)代碼依舊報(bào)同樣的錯(cuò)誤

    CU采用的Discuz論壇程序，處理$$的時(shí)候有個(gè)bug，10樓的代碼已重新編輯，你再試試。

您那個(gè)代碼我直接復(fù)制可以執(zhí)行，但是弄到我這個(gè)代碼里就報(bào)錯(cuò)

set: Variable name must begin with a letter.

以下是我的全部代碼
#!/bin/csh

set pibyt1 = `sed -n 16p /usr/local/scripts/all.txt`
set pibyt2 = `sed -n 17p /usr/local/scripts/all.txt`
set pibyt3 = `sed -n 18p /usr/local/scripts/all.txt`
set pibyt4 = `sed -n 19p /usr/local/scripts/all.txt`
set pibyt5 = `sed -n 20p /usr/local/scripts/all.txt`

foreach i (pibyt1 pibyt2 pibyt3 pibyt4 pibyt5)
    eval set x=\$$i
    if ( $x > 1000000000 )  then
        set y =`echo | awk 'BEGIN{printf "%.2f\n", '$x'/1000/1000/1000}'`
        set y = $y"GB"
    else
        set y =`echo | awk 'BEGIN{printf "%.2f\n", '$x'/1000/1000}'`
        set y = $y"MB"
    endif
end
echo pibyt1
echo pibyt2
echo pibyt3
echo pibyt4
echo pibyt5

執(zhí)行出來(lái)了，是空格的事情，但是我怎么將處理后的數(shù)據(jù)分別再賦予回原來(lái)的變量呢？
