字符串我想建立像在變量小零件下面建設外殼採用特殊字符
sqoop export --connect jdbc:db2://xx.xx.xx.xxx:50000/DB1 --username user1ib2c --password pass123! --table table1 --export-dir /user/hduser
我已初步存儲東西的命令，然後嘗試在文件，如下合併
sqoop_cmd1="sqoop export --connect $target_db_url"
sqoop_cmd2="--username $db_user_nm"
sqoop_cmd3="--password $db_password"
sqoop_cmd4="--table $tbl_nm_upr --export-dir $export_dir"
`echo $sqoop_cmd1` > $sqoop_cmd
`echo $sqoop_cmd2` >> $sqoop_cmd
`echo $sqoop_cmd3` >> $sqoop_cmd
`echo $sqoop_cmd4` >> $sqoop_cmd
但像下面
script1.sh: line 77: --username: command not found
script1.sh: line 78: --password: command not found
script1.sh: line 79: --table: command not found
這我使用的shell腳本得到錯誤：

的配置文件來運行它，如下：

bigsql_password=pass123
使用echo與「-n」fla g並且在每個cmd_value的末尾都有空格。 – Jas
我希望你正在聲明$ target_db_url，$ db_user_nm和你在sqoop_cmdN變量中使用的其他變量。你也不需要反引號來包圍'echo'並使用帶有「-n」標誌的echo。 – Jas
「我不明白當他們做了我沒有想到的事情時，會發生什麼反作用並且感到驚訝。」把它們拿出來。 – tripleee
