如何在ksh中抑制grep

Question

我有以下程序

query=$selectPart"${indxFile}"$filePart

if find /home/test -name "${cobolFile}"| xargs grep $query;then
   print "${cobolFile}"
    while read -r scriptFile;do
        print " "

    done < listScripts.txt

但是grep查询的输出正在打印到stdout。如何抑制此输出？

Answer 1

以下内容应该有效

if find /home/test -name "${cobolFile}"| xargs grep $query | grep -v grep;then

Answer 2

if find /home/test -name "${cobolFile}"| xargs grep -q $query;then

这个shd做的伎俩：D

Answer 3

if [ "$(find /home/test -name "${cobolFile}" -exec grep $query {} + )" ]
then
  print "${cobolFile}"
  while read -r scriptFile
  do
    print " "
  done < listScripts.txt
fi
