Sometimes I think of some neat things I've done over the years and
just feel like sharing.<br>
<br>
Here are a few: (linux OS)<br>
<font face="Courier New, Courier, monospace"><br>
Merge PDFs into a single new PDF:<br>
/usr/bin/gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite
-sOutputFile=file_new.pdf file1.pdf file2.pdf<br>
<br>
Extract Pages from a PDF:<br>
i.e. page 1-4<br>
/usr/bin/gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dFirstPage=1
-dLastPage=4 -sOutputFile=file_new.pdf file1.pdf<br>
<br>
Extract Pages from page # to end: <br>
/usr/bin/gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dFirstPage=2
-sOutputFile=file_new.pdf file1.pdf<br>
<br>
Get the numbers of pages in a PDF:<br>
/usr/bin/pdfinfo file1.pdf | grep "Pages:" | sed s/"Pages:"//g |
sed s/" "//g<br>
i.e.<br>
8<br>
<br>
Get the Lat/Long from a JPG image:<br>
exiftool -n -gpslatitude -gpslongitude file2.JPG<br>
i.e.<br>
GPS Latitude : 31.4998652777778<br>
GPS Longitude : -100.448014444444</font><br>
<br>
I hope someone finds this useful.<br>
<br>
Be safe out there,<br>
