find usage with parameters
i have this basic piece of code to look for an aging file based on an input parameter.

Code:
pfile=$1
pdir=`pwd`
echo current directory $pdir

for i in `find . "$pfile" -mtime +540`
do
echo aging files $i
done

# put a white space
echo

the above code works and gives me the listing of files. i need the days as parameter too and i have included on the code another variable pday=$2.

Code:
pfile=$1
pday=$2
pdir=`pwd`
echo current directory $pdir

for i in `find . "$pfile" -mtime +$pday`
do
echo aging files $i
done

# put a white space
echo

when i run the code it failed

Code:
$ sh rm_aging_file.sh lpa_load_oscm161*.log 360
current directory /export/home/lpaftdv/data/log
find: 0652-086 Specify a decimal integer for -mtime
Usage: find [-H | -L] Path-list [Expression-list]

how do i include the day parameter to make it work?

thanks,
warren

Hi.

Your original script does not work, actually (not without specifing the -name option with the filename).

Code:
for i in `find $pdir -name "$pfile" -mtime +$pday`

But...

If you pass in a wildcard like "lpa_load_oscm161*.log", then the shell will expand it.

Therefore what you think is $2 (pday) is actually the second filename in the expanded list "lpa_load_oscm161*.log".

You should quote the first argument:

i.e.
Code:
sh rm_aging_file.sh "lpa_load_oscm161*.log" 360

i change the code to this:

Code:
pfile=$1
pday=$2
pdir=`pwd`
echo current directory $pdir

for i in `find -name "$pfile" -mtime +$pday`
do
  echo aging files $i
done

# put a white space
echo

the script failed when i run

Code:
$ sh rm_aging_file.sh "lpa_load_oscm161*.log" 360
current directory /export/home/lpaftdv/data/log
Usage: find [-H | -L] Path-list [Expression-list]

thanks.

You removed the directory...

Code:
find -name "$pfile" -mtime +$pday

Should be
Code:
find . -name "$pfile" -mtime +$pday
or
find $pdir -name "$pfile" -mtime +$pday

i thought that when removing the directory will work since it does not require any parameter for the directory. putting the directory inside the find command it works.

Code:
pfile=$1
pday=$2
pdir=`pwd`
echo current directory $pdir

for i in `find $pdir -name "$pfile" -mtime +$pday`
do
  vfile=`basename $i`
  echo aging files $vfile
  
done

# put a white space
echo

Code:
$ sh rm_aging_file.sh "lpa_load_oscm161*.dat" 360
current directory /export/home/lpaftdv/data/archive
aging files lpa_load_oscm161_20070814.dat
aging files lpa_load_oscm161_20071002.dat
aging files lpa_load_oscm161_20071116.dat
aging files lpa_load_oscm161.dat

$

i have to add a code that if the command returns nothing it will echo a message "no aging files found that are 360 days old".

in pseudocode:
Code:
if `find $pdir -name "$pfile" -mtime +$pday` returns null
   echo "no aging files found that are 360 days old"
else
   ...
end if

how do i check if the `find $pdir -name "$pfile" -mtime +$pday` command returns value or none at all? thanks.

Hi.

Find doesn't return an error when it doesn't find anything, so one solution would be:

Code:
C=0
pfile=$1
pday=$2
pdir=`pwd`
echo current directory $pdir

for i in `find $pdir -name "$pfile" -mtime +$pday`
do
  let C=$C+1
  vfile=`basename $i`
  echo aging files $vfile

done
if [ $C -eq 0 ]; then
  echo "No files found."
  ...
fi

# put a white space
echo

Alternatively, grep does return an error, so you can do this:
Code:
pfile=$1
pday=$2
pdir=`pwd`
echo current directory $pdir

for i in `find $pdir -name "$pfile" -mtime +$pday | grep .`
do
  vfile=`basename $i`
  echo aging files $vfile

done
if [ $? -ne 0 ]; then
  echo "No files found."
  ...
fi
# this will only work if the last command in your loop doesn't return an error


# put a white space
echo

thank you and it works. i used the first example you posted and i was able to get the expected results.

Code:
pfile=$1
pday=$2

vdir=`pwd`
vctr=0
echo current directory $vdir

for i in `find $vdir -name "$pfile" -mtime +$pday`
do
  let vctr=$vctr+1
  vfile=`basename $i`
  echo aging files $vfile
done

if [ $vctr -eq 0 ]; then
  echo "no aging files found that are $pday days old"
fi

# put a white space
echo

Code:
$ sh rm_aging_file.sh "lpa_load_oscm161*.dat" 360
current directory /export/home/lpaftdv/data/archive
no aging files found that are 360 days old

$ sh rm_aging_file.sh "lpa_load_oscm161*.dat" 180
current directory /export/home/lpaftdv/data/archive
aging files lpa_load_oscm161_2008085.dat
