pdfjoin:tldr:4f33f

The command you provided is an example of a command using the "pdfjoin" utility.

Here is a breakdown of the command's components:

1. "pdfjoin": This is the name of the utility or program being run.
2. "${filename-pdf}": This is a variable that represents the name of the PDF file you want to join. The specific value of this variable is not given in the command you provided.
3. "${3-5,1}": This is another variable, representing a range of pages from the PDF file. In this case, it represents pages 3 to 5, in sequence (3, 4, 5), and page 1 separately. Again, the specific values of these variables are not provided in the given command.
4. "--suffix ${rearranged}": This option is used to specify a suffix for the output file(s). In this case, the suffix is given by the ${rearranged} variable. Once more, the specific value of this variable is not provided.

Overall, this command seeks to join specific page ranges (pages 3 to 5 and page 1) from a PDF file (specified by the ${filename-pdf} variable) into a single output file. The output file(s) will have a suffix specified by the ${rearranged} variable. However, without the specific values of these variables, it is difficult to determine the exact functionality of this command.
