Find: missing argument to `-mtime'

this find command works when using manually on the command line
Code:
--
$ ls -latr file*.log
-rw-r--r-- 1 oracle dba 75 Jan  4 05:00 file_2.log
-rw-r--r-- 1 oracle dba 75 Jan  4 05:00 file_1.log
$
$ find . ! -name -prune -type f -name "file*.log" -daystart -mtime 2
./file_1.log
./file_2.log
$


however when using it on a on bash shell script as
Code:
...
for i in `find . ! -name . -prune -type f -name "$vfile" -daystart -mtime +$pday`
...

where the variable $vfile is the first parameter for the file to search and $pday is the second parameter days how old is the file

it is getting the error
Code:
$ sh rmAgingFile.sh file*.log 2
current directory .
find: missing argument to `-mtime'
no aging files found that are file_2.log days old

please help thank you.

Linux version: 2.6.32-754.15.3.el6.x86_64

This is telling you that the value for pday is not set or not an integer, so your command as a whole becomes invalid. Could you sh -xv rmAgingFile.sh file*.log 2 and review the output to see what is actually being run? Do you actually assign the argument 2 to that variable pday ? I presume it would need something like pday="${2}" early in your code to do that.

It might also be that the shell where you are running the command has expanded file*.log to each file it found, so that might mess up the input. You could try by wrapping it in double quotes, so sh -xv rmAgingFile.sh "file*.log" 2 might be better. Obviously drop the -xv if this does the trick.



If this is still failing, could you paste the output/errors showing the expanded find command as it is trying to run?




Kind regards,
Robin

originally it was written on AIX and is working fine then had to moved the to same script to Linux. basically the goal of the script is to find a file that is days old depending on the parameter.

here is the output using this command sh -xv rmAgingFile.sh file*.log 2
Code:
p1=$1
+ p1=file_1.log
pday=$2
+ pday=file_2.log

vdir=`pwd`
pwd
++ pwd
+ vdir=/sbin/scripts
vhomedir=`pwd`
pwd
++ pwd
+ vhomedir=/sbin/scripts
vctr=0
+ vctr=0

# check for null parameter
if [ $# -lt 1 ]; then
  echo current directory $vdir
  echo no parameter entered
  echo
else
  #check for directory entry only
  if [ -d $p1 ]; then
    vdir=$p1
    echo current directory $vdir
    cd $vdir
    echo no file parameter entered
    echo
  #check for directory entry and file
  elif [ -f $p1 ]; then
    vdir=`dirname $p1`
    echo current directory $vdir
    cd $vdir

    for f in $1
    do
      vfile=`basename $f`
      #for i in `find $vdir -name "$vfile" -mtime +$pday`
      #ommit the subdirectories in the searcch
      for i in `find . ! -name . -prune -type f -name "$vfile" -daystart -mtime +$pday`
      do
        let vctr=$vctr+1
        vfile=`basename $i`
        echo deleting aging files $vfile
        rm $vfile
      done
    done

    if [ $vctr -eq 0 ]; then
      echo "no aging files found that are $pday days old"
    fi
  else
    echo $p1 not found
  fi
fi
+ '[' 3 -lt 1 ']'
+ '[' -d file_1.log ']'
+ '[' -f file_1.log ']'
dirname $p1
++ dirname file_1.log
+ vdir=.
+ echo current directory .
current directory .
+ cd .
+ for f in '$1'
basename $f
++ basename file_1.log
+ vfile=file_1.log
find . ! -name . -prune -type f -name "$vfile" -daystart -mtime +$pday
++ find . '!' -name . -prune -type f -name file_1.log -daystart -mtime +file_2.log
find: missing argument to `-mtime'
+ '[' 0 -eq 0 ']'
+ echo 'no aging files found that are file_2.log days old'
no aging files found that are file_2.log days old

#return the cursor to the home directory
cd $vhomedir
+ cd /sbin/scripts

# put a white space
echo
+ echo


thank you.

Exactly what rbatte1 predicted
Quote:
the shell where you are running the command has expanded file*.log
is happening: $2 is becoming the second file found / expanded to.

tried this still don't work.
pday="${2}"

maybe I am doing it wrong.

Don't quote $2 but the first parameter (the one with wild card chars) on the command line when calling the script.

tried to wrap the first parameter with double quotes but still would not work.
