#7004 — Converting multiple PNG files to single PDF from BASH

Hi guys,
I am looking for a bash script using 'convert' to convert PNG file to single PDF.
The problem is mainly related to their names which are not numerically sorted:
fig1.png fig2.pnf fig3.png ... fig10.png... fig100.png... fig250.png

The following command creates a PDF file with useless *unsorted* pages:

convert *png book.pdf

It seems that there is no option for the 'convert' to force the piping into a single file..

The following script for the first 20 pages, on the other hand, creates only a single page as output, the last one:

for i in $(seq 20); do convert fig$i.png book.pdf; done

Any suggestion?

pdftk

I cannot give you a recipe, but that took will almost certainly have a way 
to fix your problem.

The shell sorts generated filename lists.  Use multiple patterns:

  convert fig?.png fig??.png fig???.png book.pdf

Or use ls to sort them in numerical ("version") order:

convert $(ls -v fig*.png) book.pdf

or maybe you want to sort them by date:

convert $(ls -tr fig*.png) book.pdf

Or by size:

convert $(ls -S fig*.png) book.pdf

(just kidding)

Thank you Tim,

I guess the problem is related to the 'enumeration' of such files, and pdftk has the same limitation of the convert command: once it has executed, the output does not follow the natural numeration fig1* fig2* .. fig10* but the following:

fig10.png
fig11.png
fig12.png
fig13.png
fig14.png
...
fig19.png
fig1.png
fig20.png
...

well thats a bit of awk or shell or summat to sort them ..

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to 
lead are elected by the least capable of producing, and where the 
members of society least likely to sustain themselves or succeed, are 
rewarded with goods and services paid for by the confiscated wealth of a 
diminishing number of producers.

ah well, let's try it for a start, here's a PoC of a possible way:
----------
$ ls | awk '
{
  ix=sprintf("%020d",0+$NF)
  nym[ix $0]=$0
}
END{
  for(i in nym) print i,nym[i]
}
' FS='[a-zA-Z]*' | sort -n | cut -d" " -f2- | tr '\n' ' ' && echo ""
----------

since you're interested in learning "summat" aka "kinashellstof"
it might be an interesting POV to use 4 and a half tool off the box
in that example ;-)
(you may do it strictly in awk but with that starter it may add
up some problems (like adding asort[i] (¹)) if you're a genuine rookie(b)
and were not just being tongue in tail or cheek against 'zipeppe' ;-)

 Note that this PoC goes a different path than the 'ls -v' solution (*)
(which I'd think would be the best one in the case exposed but as you
asked for some information about how...) just for the sake of it and
in the case it'd be of some use (at least the idea not the code fershure)



¹ hence needing not much further obfuscation if (b) true ;D)

(*) any doubt about that point, make/goto some disposable dir and play with:
$ for ll in {7..13} ; do touch "ff$ll" "fff$ll" "fg$ll" ; done

PMS:
 xposting to `cla` since the PoC is quite based on awk but FU2 kept in place

That has nothing to do with pdftk or convert. The * expansion is done by
the shell, long before the commands see the arguments. And the ordering
IS lexicagraphical. . occurs in the sort order AFTER all numbers, not
before. So it is sorted after the numbers. 1. comes after 19

No, that is sorted. It is lexigraphically sorted. It is in fact very
hard to sort numbers as you have given them 
You could do
convert fig[0-9].png fig[0-9][0-9].png fig[0-9][0-9][0-9].png book.pdf

of course. Each time you run it, it replaces book.pdf with a new one.

Use rename twice:

$ $ rename -V
rename from util-linux 2.22.1
$ rename fig fig0 fig?.png
$ rename fig fig0 fig??.png

$ ls -1
fig001.png
fig002.png
fig003.png
..
fig010.png
..
fig100.png
..
fig250.png

Or use awk to build a file renaming script:

$ ls *.png |
awk -v digits=3 -v Q="'" '
{
prefix="";number="";suffix="";
prefix=substr($0,1,match($0,"[0-9]")-1);		# part before digits
number=substr($0,length(prefix)+1);
number=substr(number,1,match(number,"[^0-9]|$")-1);	# digits part
suffix=substr($0,length(prefix)+length(number)+1); 	# part after digits
if (number!="") {
	printf "mv " Q "%s" Q "\t" Q "%s%0" digits "s%s" Q "\n",
		$0, prefix, number, suffix;
} else { print "#"$0; }
}
'
mv 'fig1.png'   'fig001.png'
mv 'fig10.png'  'fig010.png'
mv 'fig100.png' 'fig100.png'
mv 'fig2.png'   'fig002.png'
mv 'fig250.png' 'fig250.png'
mv 'fig3.png'   'fig003.png'

Available as a package on most major distributions.

QUOTE

  mmv is a program to move/copy/append/link multiple files
  according to a set of wildcard patterns. This multiple
  action is performed safely, i.e. without any unexpected
  deletion of files due to collisions of target names with
  existing filenames or with other target names.
