pdfseparate:tldr:dc42f
The command you provided is using a tool called "pdfseparate" to split a PDF file into multiple individual pages.
Here is a breakdown of the command:
-
"pdfseparate": This is the name of the command-line tool that is being executed. It is used to separate pages from a PDF file.
-
"-f ${3}": This is an argument passed to the "pdfseparate" command. The "-f" flag specifies the first page to be extracted from the PDF file. "${3}" represents a variable, where the value of the variable is expected to be provided when running the command. This value should be the desired starting page number.
-
"${path-to-source_filename-pdf}": This is another variable representation. It should be replaced with the actual path to the PDF file you want to split. Make sure to include the file name and extension.
-
"${path-to-destination_filename-%d-pdf}": This is again a variable representation. Replace it with the path and desired name format for the output files. The "%d" is a placeholder that will be replaced with the page number, and the "-pdf" is added to the end of each generated file. For example, if you set the path to "/path/to/output/file-", the resulting files will be named as "file-1.pdf", "file-2.pdf", etc.
In summary, the command is using "pdfseparate" to split a PDF file starting from a specified page number. The resulting pages will be saved as individual PDF files using the provided output file format.
