標(biāo)題: 【求助】HP-UX下判斷FTP腳本輸出結(jié)果不對(duì)
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* ]];

如果FTP開(kāi)啟，則檢查ftpaccess配置是否合規(guī)。ftpaccess合規(guī)是通過(guò)判斷文件中是否包含restricted-uid決定是否合規(guī)。
現(xiàn)在的問(wèn)題是，不管ftpaccess中是否包含restricted-uid行，輸出結(jié)果都為true。但是單獨(dú)執(zhí)行以下內(nèi)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(jié)果是正確的，這是為什么呢？
