No such file or directory

[frepie]

Need help on a very simple shell script to convert video from wmv to mp4 format.

#!/bin/bash

for i in *.wmv;
do
    name=`echo $i | cut -d'.' -f1`;
    avconv -i "$i" -vcodec libx264 -acodec aac -strict experimental  -threads 3 "$name.mp4";
done

The folder only contains wmv video but when I run it, I get the error :

*.wmv: No such file or directory

yet there are dozens of wmv files, that show up when I do

ls -l *.wmv

but somehow, *.wmv fails to work in the script.

Something like this, perhaps;

#!/bin/bash

FILES=/path/to/files

for f in $FILES
do
  # take action on each file
done

I appreciate your quick reply but I would like to know why *.wmv is not recognized in the script while it works on the command line.

Not sure why your script does not work. Are you in the right directory when you run it?


Linux is very permissive with file names. To prevent any unexpected behaviour, I would try something like:

#!/bin/bash

#with this option *.wmv will also match .WMV .Wmv .wmV ... 
shopt -s nocaseglob

#don't run the for loop if there are no wmv files in the current working directory
shopt -s nullglob

for file in ./*.wmv
do
    name=${file%.*}
    echo "$name" "$file"
done

I am puzzled....
The complete script that failed was as follows (I just didn't copy the commented lines in the first post):

#!/bin/bash

#for %%f in {*.avi} do {
#avconv -i "%%~nxf" -c:v libx264 "%%~nf.mp4"
#}

for i in *.wmv;
do
    name=`echo $i | cut -d'.' -f1`;
    avconv -i "$i" -vcodec libx264 -acodec aac -strict experimental  -threads 3 "$name.mp4";
done

Now the script is

#!/bin/bash

for i in *.wmv;
do
    name=`echo $i | cut -d'.' -f1`;
    avconv -i "$i" -vcodec libx264 -acodec aac -strict experimental  -threads 3 "$name.mp4";
done

The only thing I did was delete the comment lines. And now, it works.....
