Question

我在UNIX shell脚本编写中使用generate_vendor_info.ksh名称编写了以下代码。

#!/usr/bin/ksh

sqlplus -s tips/tips@tipstest<< EOS

SET NEWPAGE 0
SET SPACE 0
SET LINESIZE 135
SET PAGESIZE 0
SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET WRAP OFF
SET MARKUP HTML OFF SPOOL OFF

spool vendor_info.dat
select 'B','|',to_char(sysdate,'YYYYDDMM') from dual;
select 'H','|',vendor_id,'|', case config_code when 'DASN' then 'ASNVENDOR' when 'VASN' then 'VCDVENDOR' END,'|', case config_value when 'Y' then 'Y' when 'N' then 'N' END,'|',to_char(updated_date,'YYYYDDMMHH24MISS') from tips_vendor_config_msi,dual where updated_date >= sysdate-19 and (config_code in ('DASN','VASN')) order by updated_date desc; 
select 'E','|',ltrim(count(*)+2) from tips_vendor_config_msi,dual where updated_date >= sysdate-19 and (config_code in ('DASN','VASN'));
spool off;

spool store_info.lst
select distinct(ltrim(s.store)) from tips_store_config_msi s where s.store='3753' order by s.store;
spool off;

EOS

TIMESTAMP=`date +"%C%y%m%d%H%M%S"`

for StoreNO in `cat store_info.lst`
  do
       FILENAME="$(echo ${StoreNO}.${TIMESTAMP})"
       ORIGINAL_FILE="vendor_info.dat"
       NEW_FILE="$(echo ${ORIGINAL_FILE}.${FILENAME})"
       cp $ORIGINAL_FILE $NEW_FILE
       echo $NEW_FILE       
done

当我执行shell脚本时，我得到如下结果。

**generate_vendor_info.ksh[33]: cat:  not found**

Answer 1

出现错误消息表明您的shell脚本无法找到cat命令。

要进行调试，请使用命令ksh -xv generate_vendor_info.ksh在详细调试模式下运行ksh。

另外，您是否有理由在不必要的子shell中调用不必要的echo命令？您撰写了FILENAME="$(echo ${StoreNO}.${TIMESTAMP})"，但这可以更简单地表达为FILENAME="${StoreNO}.${TIMESTAMP}"，并在您设置NEW_FILE的位置进一步表达相同的两行。

cat：执行ksh脚本时找不到
