bashlinuxscript
i need to change a string to interger, because i check the size of file (extract with : stat -c%s $filename) with a number, follow the complete script :
#!/bin/bash
# Variable that contain path destination file
path=/sobstitude
# Variable for size
size=1000
# Loop for file scan
for filename in /test/*;
do
# Take the size of file
filesize=$(stat -c%s $filename)
# Check if the file is empty
if [ $filesize > $size ]
then
# Replace file
mv $filename $path
fi
done
exit 0;
I tried a few cases, and seems it works as you need:
Shell script, usr/bin/perl, pass input as arguments.
use File::Find;
find({ wanted => \&find_files, no_chdir => 1 }, @ARGV);
sub find_files
{
if (-f $_)
{
($file) = $_ =~ /.*\/(.*)$/;
push (@all_files, $_) if ($file ne ".DS_Store");
}
else
{
push (@all_folders, $_);
}
}
sub osascript($) { system 'osascript', map { ('-e', $_) } split(/\r/, $_[0]); }
foreach(@all_files)
{
@paths = split(/\//, $_);
for $i (0..$#paths-1)
{
if ($i == 0)
{
$x = "$paths[$i]";
}
else
{
$x = "$last[$i-1]/$paths[$i]";
}
push(@last, $x);
$temp{$x} ++;
}
@last = ();
}
@not_gray_folders = keys %temp;
foreach(@all_folders)
{
$folder = $_; $flag = 0;
foreach(@not_gray_folders)
{
if ($folder eq $_)
{
$flag = 1;
}
}
if (!$flag)
{
$label = 7;
}
else
{
$label = 0;
}
&osascript ("tell application \"Finder\" to set label index of alias POSIX file \"$folder\" to $label");
}
The date command is quite flexible in recognizing strings that represent dates. So, for example:
$ date -d 'Oct 29 2018'
Mon Oct 29 00:00:00 CET 2018
The -d flag instructs date to display the date given to it as a string.
You can add the +FORMAT parameter to convert the date as you like. For example:
$ date -d 'Oct 29 2018' '+%Y-%m-%d'
2018-10-29
Refer to man date for the option you have to set the output format.
EDIT:
Sorry, I didn't get your reference to -mtime. Are you talking about the find filter? If so, I guess you need the difference between today and your OLDEST_DATE, in days.
You can obtain it by converting dates to the Epoch format (seconds since 1970-01-01 00:00:00 UTC). For example:
$ current="$(date '+%s')"
$ oldest_date_epoch="$(date -d "$OLDEST_DATE" '+%s')"
$ diff_days=$(( ("$current" - "$oldest_date_epoch") / (3600 * 24) ))
Note this is not a general solution, since date cannot understand foreign languages.

In
bash/shvariables contain strings, there is no strict concept of integers. A string may look like an integer and it's enough.stat -c%s $filenameshould return a string that looks like an integer.In your case the main problem is in the redirection operator
>(you probably now have files with names that are numbers in the working directory). This snippet:should be
