所以我想在bash中得到期望的正常工作。預計在特殊字符的bash腳本2部分
這裏是腳本內容...
[[email protected] ~]# cat mysql_repl.sh
#!/bin/bash
read -p "Master server ip: " masterip
read -p "What is the regular user to log into the master server: " masteruser
read -p "What is the password for the regular user for the master server: " masterpass
read -p "What is the root password for the master server: " masterrootpass
read -p "Slave server ip: " slaveip
read -p "What is the regular user to log into the slave server: " slaveuser
read -p "What is the password for the regular user for the slave server: " slavepass
read -p "What is the root password for the slave server: " slaverootpass
expect -c "set slaveip $slaveip;\
set slaveuser $slaveuser;\
set slavepass $slavepass;\
set timeout -1;\
spawn /usr/bin/ssh $slaveip -l $slaveuser 'ls -lart';\
match_max 100000;
expect *password:;\
send -- $slavepass\r;\
interact;"
下面是腳本的輸出...
[[email protected] ~]# ./mysql_repl.sh
Master server ip:
What is the regular user to log into the master server:
What is the password for the regular user for the master server:
What is the root password for the master server:
Slave server ip: xxx.xxx.xxx.xxx
What is the regular user to log into the slave server: rack
What is the password for the regular user for the slave server: test
What is the root password for the slave server: DVJrPey99grJ
spawn /usr/bin/ssh 198.61.221.179 -l rack 'ls -lart'
[email protected]'s password:
bash: ls -lart: command not found
該命令沒有正確執行。我也試過/ bin/ls，但它仍然無法找到它。
第二部份...同一腳本...
我有一個變量在bash，具體而言，一個密碼。在這種情況下，密碼是「as $ 5！@？」 我想要做的是穿過每個角色，測試它是否是特殊角色並逃離它。因此，例如...
[email protected]?
我至今接近但不工作的特殊字符，這將對於非特殊工作...
echo -n $pass | while read -n 1 c; do [[ "$c" = [[email protected]#$%^&*().] ]] && echo -n "\\"; echo -n $c; done
人對如何我的想法可以在每個特殊字符前加一個\？
希望能夠澄清問題。
[這是不是你想要解決的問題。（http://mywiki.wooledge.org/XyProblem） –
那麼什麼我想要做的是在bash腳本中使用'expect -c'，因爲我在bash中很體面，但對期望一無所知。我正在讀取用戶的密碼，然後將該密碼分配給一個變量。我將這個密碼輸入「」「expect -c」set timeout -1; \ spawn ssh $ {slaveip} -l $ {slaveuser}'ls -lart'; \ match_max 100000; expect * password：*; \ send - $ {slavepass} \ r; \ interact;「 – user1601716
您試過引用它嗎？ –
