The Portable Document Format (PDF) is a widely recognized document format known for preserving content layout. There are times when individuals or professionals need to consolidate multiple PDFs into one, and while graphical tools are abundant, the command line provides an efficient and scriptable alternative for this task.
Several software solutions offer command line interfaces for merging PDFs. Here are some of the most recognized:
pdfuniteutility, is designed for merging PDFs.
To merge PDFs with pdftk, use the following syntax:
pdftk file1.pdf file2.pdf cat output combined.pdf
This command takes
file2.pdf, merges them, and outputs the result to
Ghostscript provides a slightly more complex, but powerful way to combine PDFs:
gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=combined.pdf file1.pdf file2.pdf
This command will produce a merged PDF named
combined.pdf from the input files.
Merging PDFs via the command line is a robust, flexible, and efficient approach, especially for those comfortable with CLI operations or those in need of automation. As with any task, understanding the tools and their parameters will ensure the best results.
