This single command is not working in BKWP64's terminal???

Post by Clarity »

I am booted to BKWP64 v1008 by @radky.

IN a terminal, I am overlooking something.

Scenario:

  1. I am trying to pipe the output into opening the geany command.
    find . -name "*.iso" -mtime -30 | geany -

  2. In bash, I thought the "-" argument tells the command to read the input from standard input (stdin), which is where the piped output is coming from.

  3. But, this is not working because geany opens to an empty file named "-"?

Works fine if I pipe to a file and geany opens the file, but can I do this without the intermediate file?
What understanding am I missing?

Edit: Hummm??? Maybe geany 'must' not be able to accept input way??? Could that be right?

I've always taken the long way and redirected the output to a file and then opened the file.

Looks like this is still an open issue too: https://github.com/geany/geany/issues/780

could do a long double command:

Code: Select all

find . -name "*.iso" -mtime -30 | names.txt &;  geany names.txt

Don't know if that ampersand is needed or not.

Did you test this yourself first?

Yes, good point, so I tested it, and I had it wrong, instead of piping to the text file the correction should look like this:

Code: Select all

find . -name "*.iso" -mtime -30 > names.txt;  geany names.txt

The ampersand should NOT be there, it tanks the command. The above produces this output file and opens it with geany:

names.txt:

Code: Select all

./KLV-Airedale-sr15.iso

Interesting though, I had two .iso files in that directory and it only listed the first one. What does the -30 option mean? Less than 30 days old?

answer, yes that must be it, because I changed it to -120 and it listed both files, the Spectr.iso being dated 08-09 and the Airedale.iso dated 09-26:

Code: Select all

./KLV-Spectr-sr3.iso
./KLV-Airedale-sr15.iso

Your command will not work in any terminal

2. In bash, I thought the "-" argument tells the command to read the input from standard input (stdin), which is where the piped output is coming from.

Has nothing to do with bash. What argument a command uses to indicate reading from stdin - if this is supported at all - depends on the command's syntax. Could be "-", could be "-s" (e.g. gtkdialog), could be "-file -" or could be nothing at all.

What understanding am I missing?

You are missing that Geany doesn't support reading from stdin. You could use Leafpad instead. This would work:
find . -name "*.iso" -mtime -30 | leafpad
