Use pdfjam on several dozens of files

I am trying to make it easier to combine more than just a few pdf files with pdfjam:

pdfjam c1.pdf c2.pdf ... c100.pdf -o outfile.pdf

Here we got 100 files that should be merged. How can I shorten this command by using some kind of sequence command or reading out the files from the folder or something like this? I do not want to write all 100 file names by hand.

What does not work, but still explains what I am looking for is

pdfjam c{1..100}.pdf -o outfile.pdf

You can try this

echo pdfjam c{1..4}.pdf -o -o outfile.pdf | bash

or 

echo -n "pdfjam " ;for (( i=1; i<=100; i++)); do printf "c${i}.pdf "; done ; echo "-o outfile.pdf"




user@host:/tmp/pythontest$ echo -n "pdfjam " ;for (( i=1; i<=4; i++)); do printf "c${i}.pdf "; done ; echo "-o outfile.pdf"
pdfjam c1.pdf c2.pdf c3.pdf c4.pdf -o outfile.pdf


user@host:/tmp/pythontest$ echo -n "pdfjam " ;for (( i=1; i<=10; i++)); do printf "c${i}.pdf "; done ; echo "-o outfile.pdf"
pdfjam c1.pdf c2.pdf c3.pdf c4.pdf c5.pdf c6.pdf c7.pdf c8.pdf c9.pdf c10.pdf -o outfile.pdf
