RedHat Check file presence and delete other file
Hello,

I have file all_file.txt
at the end of process this file all_file.txt should be deleted only if there is no file present in dir /all_file/tmp/ or in it's sub directory.

can you please help me with the peace of code for this.

Thanks

Code:
if [ `find /all_file/tmp -type f|line`"X" = "X" ]
 then
  rm all_file.txt
 fi

The 'find' will find all files, 'line' just lets one file name through (for speed and stability), but if there is a first file, its name will be concatenated to "X" and the compare fails.

Code:
#!/usr/bin/ksh
if [ `find /all_file/tmp  -type f -prune -name "*.txt" |line`"X" = "X" ]
 then
  rm all_file.txt
 fi


but if there is a first file, its name will be concatenated to "X" and the compare fails. - Can you explain this more.
