I want to convert a bunch of jpeg files to one pdf file. The files are in a numbered format: 

```
gls -v 2014-2015-2016_R_TR-4_all_170213*.jpeg

```

gives: 

```
'2014-2015-2016_R_TR-4_all_170213 1.jpeg'  
'2014-2015-2016_R_TR-4_all_170213 2.jpeg'
'2014-2015-2016_R_TR-4_all_170213 3.jpeg'
'2014-2015-2016_R_TR-4_all_170213 4.jpeg'
'2014-2015-2016_R_TR-4_all_170213 5.jpeg'
'2014-2015-2016_R_TR-4_all_170213 6.jpeg'
'2014-2015-2016_R_TR-4_all_170213 7.jpeg'
'2014-2015-2016_R_TR-4_all_170213 8.jpeg' 
'2014-2015-2016_R_TR-4_all_170213 9.jpeg'
'2014-2015-2016_R_TR-4_all_170213 10.jpeg'

```

This is the order the jpegs should be shown in the pdf.

```
ls -l

```

gives

```

I tried this by 

```
convert "$file"*.jpeg "$file".pdf

```

with 

```
$file=2014-2015-2016_R_TR-4_all_170213

```

which produces the pdf file in the the wrong order (1, 10, 2, 3, ...).

My alternative approaches 

```
gls -v "$file"*.jpeg | convert "$file".pdf

```

and

```
convert $(gls -v "$file"*.jpeg) "$file".pdf

```

do not work either. Does anybody have a clue how I get this to work?
