太長了吧,哥們,自己先分析一下,加一些跟蹤
看看是哪兒出問題了,在具體提問.

怎么加跟蹤？shell下有這功能么？

db_info

在你的第2行加入set -x就可以實(shí)現(xiàn)跟蹤~~~~~

laoxia

你現(xiàn)在執(zhí)行到哪行？
或多加幾行echo 1， echo 2也可助判斷

nkliyong

laoxia  說的沒錯(cuò),多加一些echo很容易判斷程序運(yùn)行到哪兒,在哪兒出錯(cuò).

biansj

我看你的SHELL主要工作是進(jìn)行數(shù)據(jù)備份，備份前需要停掉數(shù)據(jù)庫，備份后重新啟動(dòng)數(shù)據(jù)庫，所有的命令執(zhí)行均是在前臺(tái)執(zhí)行，沒有進(jìn)行后臺(tái)工作，如果備份數(shù)據(jù)時(shí)間很長，則SHELL一致是掛在前臺(tái)執(zhí)行的，所以不會(huì)到提示符下。

你可以在一個(gè)TERM下執(zhí)行此SHELL，在另一個(gè)TERM下用PS查看你的SHELL是否運(yùn)行，如果不是這個(gè)原因，就用LAOXIA&amp;nkliyong的方法耐心一點(diǎn)一點(diǎn)試吧，頂多一個(gè)小時(shí)就能查出來。
