【求助】HP-UX下判斷FTP腳本輸出結果不對

環(huán)境：HP-UX rx2660a1 B.11.31 U ia64 0597325983 unlimited-user license
SHELL：/sbin/sh

1. #!/sbin/sh
   
2. FTPSTATUS=`netstat -an|grep tcp|awk '($4=="*.21") {print $0}'|wc -l`
   
3. Check_ftpaccess ()
   
4. {
   
5. if [[ "$(uname -r)" = B.10* ]];
   
6.   then ftpaccess=/etc/ftpaccess;
   
7.   else ftpaccess=/etc/ftpd/ftpaccess;
   
8. fi;
   
9. if [[ `grep -v "^#" $ftpaccess|egrep "restricted-uid|restricted-gid"|wc -l` = 0 ]];
   
10.          then echo "FTP is running.$ftpaccess is not recommended.FTP check result:false.";
    
11.          else echo "FTP is running.$ftpaccess is recommended.FTP check result:true.";
    
12. fi
    
13. }
    
14. if [[ $FTPSTATUS = 0 ]];
    
15.   then echo "FTP is not running.FTP check result:true.";
    
16.   else Check_ftpaccess;
    
17. fi;

復制代碼

如果FTP開啟，則檢查ftpaccess配置是否合規(guī)。ftpaccess合規(guī)是通過判斷文件中是否包含restricted-uid決定是否合規(guī)。
現在的問題是，不管ftpaccess中是否包含restricted-uid行，輸出結果都為true。但是單獨執(zhí)行以下內容：

1. if [[ `grep -v "^#" $ftpaccess|egrep "restricted-uid|restricted-gid"|wc -l` = 0 ]];
   
2.          then echo "FTP is running.$ftpaccess is not recommended.FTP check result:false.";
   
3.          else echo "FTP is running.$ftpaccess is recommended.FTP check result:true.";
   
4. fi

輸出結果是正確的，這是為什么呢？
