等待（在ksh中的N进程的结束和运行另一个进程后）无法正常工作 [英] Wait (the end of N process in ksh and after run another process) dont work correctly

问题描述

我的脚本是：

 ＃！/ bin / ksh 
 
 WORKFLOW1 = wf_m_LOAD_ODS_DMT_FATTO_E_BSN_LETTURE_F 
 WORKFLOW2 = wf_m_LOAD_ODS_DMT_FATTO_E_ANAGRAFICA_POD_F 
 WORKFLOW3 = wf_m_LOAD_ODS_DMT_FATTI_E_QF_F 
 pmcmd startworkflow -sv $ SERVER -d $ DOMINIO -u $ USER -p $ PASSWD -f $ DIRECTORY_SEC_LEV_ELE $ WORKFLOW1& pmcmd startworkflow -sv $ SERVER -d $ DOMINIO -u $ USER -p $ PASSWD -f $ DIRECTORY_SEC_LEV_ELE $ WORKFLOW2& pmcmd startworkflow -sv $ SERVER -d $ DOMINIO -u $ USER -p $ PASSWD -f $ DIRECTORY_SEC_LEV_ELE $ WORKFLOW3& ;; 
 wait; 
 
 echoLancio creazione indici T_DMT_SEE_FT_BSN_LETTURE>> log_DMT_R1.log 
 sqlplus $ USERDBDMT / $ PASSDBDMT @ $ SIDDB @ create_index_T_DMT_SEE_FT_BSN_LETTURE.sql& 
  

我有错误：

  ./ Start_lancio_unico_ELE_DMT_INFASAMENTO_FT.sh：第27行：接近意外标记的语法错误`;'
 ./Start_lancio_unico_ELE_DMT_INFASAMENTO_FT.sh：第27行：`pmcmd startworkflow -sv $ SERVER -d $ DOMINIO -u $ USER -p $ PASSWD -f $ DIRECTORY_SEC_LEV_ELE $ WORKFLOW1& ;;'
  

为什么;是不正确的？

我想在后台运行3进程，完成后运行第3个进程。

感谢所有

解决方案

看起来这是一个bash错误，而不是一个ksh错误。您如何调用脚本？

  $ cat script.sh 
＃！/ usr / bin / ksh 
 sleep 5& ;; 
 wait; 
 echo done 
 $ ksh script.sh 
 done 
 $ bash script.sh 
 script.sh：第2行：意外标记附近的语法错误`;'
 script.sh：line 2：`sleep 5& ;;'
  

code>& 和; 是命令终止符，显然使用两者都是一个错误。参考文献： http://www.gnu.org/software/bash/manual /bashref.html#Lists

A 列表是一个序列由一个运算符';'，'&'，'&&'或'||'分隔的一个或多个管道，并且可选地由 strong> of';'，'&'或换行符。

b

my script is:

#!/bin/ksh

WORKFLOW1=wf_m_LOAD_ODS_DMT_FATTO_E_BSN_LETTURE_F
WORKFLOW2=wf_m_LOAD_ODS_DMT_FATTO_E_ANAGRAFICA_POD_F
WORKFLOW3=wf_m_LOAD_ODS_DMT_FATTI_E_QF_F
pmcmd startworkflow -sv $SERVER -d $DOMINIO -u $USER -p $PASSWD -f $DIRECTORY_SEC_LEV_ELE $WORKFLOW1 & pmcmd startworkflow -sv $SERVER -d $DOMINIO -u $USER -p $PASSWD -f $DIRECTORY_SEC_LEV_ELE $WORKFLOW2 & pmcmd startworkflow -sv $SERVER -d $DOMINIO -u $USER -p $PASSWD -f $DIRECTORY_SEC_LEV_ELE $WORKFLOW3 &;
wait;

echo "Lancio creazione indici T_DMT_SEE_FT_BSN_LETTURE">>log_DMT_R1.log
sqlplus $USERDBDMT/$PASSDBDMT@$SIDDB @create_index_T_DMT_SEE_FT_BSN_LETTURE.sql &

I have error:

./Start_lancio_unico_ELE_DMT_INFASAMENTO_FT.sh: line 27: syntax error near unexpected token `;'
./Start_lancio_unico_ELE_DMT_INFASAMENTO_FT.sh: line 27: `pmcmd startworkflow -sv $SERVER -d $DOMINIO -u $USER -p $PASSWD -f $DIRECTORY_SEC_LEV_ELE $WORKFLOW1 &;'

why ; is not correct?

i want run 3 process in background and after they are finished run a 3th process.

thanks to all

解决方案

It appears that's a bash error, not a ksh error. How are you invoking the script?

$ cat script.sh
#!/usr/bin/ksh
sleep 5 &;
wait; 
echo done
$ ksh script.sh
done
$ bash script.sh
script.sh: line 2: syntax error near unexpected token `;'
script.sh: line 2: `sleep 5 &;'

In bash, both & and ; are command terminators, and it's apparently an error to use both. Ref: http://www.gnu.org/software/bash/manual/bashref.html#Lists

A list is a sequence of one or more pipelines separated by one of the operators ‘;’, ‘&’, ‘&&’, or ‘||’, and optionally terminated by one of ‘;’, ‘&’, or a newline.
