Top Forums UNIX for Beginners Questions & Answers Find: missing argument to `-mtime' Post 303042769 by wtolentino on Monday 6th of January 2020 10:59:36 AM
Old 01-06-2020
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.

find -mtime off by one day?

If I use the find command to find files older than n days I have to enter find . -mtime +(n-1). I tried this on a Solaris 9 system and also Linux.

shtool-echo

SHTOOL-ECHO.TMP(1)					      GNU Portable Shell Tool						SHTOOL-ECHO.TMP(1)

NAME

       shtool-echo - GNU shtool echo(1) extensional command

SYNOPSIS

       shtool echo [-n|--newline] [-e|--expand] string

DESCRIPTION

       shtool echo is an echo(1) style command which prints string to stdout and optionally provides special expansion constructs (terminal bold
       mode, environment details, date, etc) and newline control. The trick of this command is that it provides a portable -n option and hides the
       gory details needed to find out the environment details under option -e.

OPTIONS

       The following command line options are available.

       -n, --newline
	   By default, output is written to stdout followed by a "newline" (ASCII character 0x0a). If option -n is used, this newline character is
	   omitted.

       -e, --expand
	   If option -e is used, string can contain special "%x" constructs which are expanded before the output is written. Currently the
	   following constructs are recognized:

	   %B  switch terminal mode to bold display mode.

	   %b  switch terminal mode back to normal display mode.

	   %u  the current user name.

	   %U  the current user id (numerical).

	   %g  the current group name.

	   %G  the current group id (numerical).

	   %h  the current hostname (without any domain extension).

	   %d  the current domain name.

	   %D  the current day of the month.

	   %M  the current month (numerical).

	   %m  the current month name.

	   %Y  the current year.

EXAMPLE

	#   shell script
	shtool echo -n -e "Enter your name [%B%u%b]: "; read name
	shtool echo -e "Your Email address might be %u@%h%d"
	shtool echo -e "The current date is %D-%m-%Y"

HISTORY

       The GNU shtool echo command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Website META Language (WML)
       under the name buildinfo. It was later taken over into GNU shtool.

       shtool(1), echo(1).
