done < $HDDATA


I am trying to create some files with filenames base on a concatenation of two variables. I must be missing something since i am getting strange results. When I check the file name to be created $FileName or $FileName1 it prints out fine.


From this


1561 - History Channel.strm
1563 - Discovery Espan.strm
1564 - Nat Geo Mundo.strm
1567 - Canal Once.strm

I also receive

./x.sh: line 33: Streams/$FileName1: ambiguous redirect
1788 - ProSiebenSAT.1W.strm
./x.sh: line 33: Streams/$FileName1: ambiguous redirect

if i try to echo the files.



Weird. have i not included something?

[CODE]while read CHANNEL; do
echo 'hdhomerun://'$HDHomeID'-0/tunner0?channel=auto:'$UScable'&program='$Program > Streams/"$ChannelNo - $FileName.strm"


Looks like double quotes on the line did the trick. Not sure why it did not work on the variable line.

[Vaphell]

any sample of the input data, especially these lines responsible for errors?

can't you split the row directly, with

while read -a array; do ...
?
It's possible the array is not required in the first place, why not

while read freq uscable _ prog channel filename; do ...
?


either way it looks like a word splitting problem. Unquoted var with space(s) gets cut to pieces and you dont redirect to > "some file" but to > "some" "file" <- ambiguous redirect. Always quote your variables.

Here is the sample data

411000000 55 55 127 109 C-SPAN
693000000 107 107 128 110 C-SPAN 2

read the file line by line and places it in an array. there weird part was that it print fine with echo. I think tried the "while read -a array; do ..." not sure what the result where, will try again.

[steeldriver]

How about something like



while read -r freq uscable _ prog _ name; do
touch tests/"$name"
done < channeldata




$ ls -l tests
