Well, what I want to achieve, well.. keep... is this:
Please understand that I'd like to replace the used echo with printf.
And
Should be the same as:
Again, TUI was refering to echo, which is the reason it worked before.
With SWARM, I'd like to keep using 'printf' as internal core output, as I'm still under the impression that NOT ALL *nix flavors provide an actual echo command.
What I currently have is this:
Which outputs to:
So only the line where the text starts with 2 seems to be working as expected, or at least, as intended.
This said, true that, for multiple lines I'd need special handling- which I think worked 'out of the box' when I had used echo...
Now you tell me to use an 'echo' function, whereas in the feedback thread the commone-tone was to NOT use functions that are labeld as regular commands, such as specificly named 'echo'.
Regardless, if no echo exists, I could 'load' a function named echo, but that still doesnt make the use of printf in that echo-function work as I hoped it would.
On the other hand, if someone could correct me and tell me i'm wrong and therefor:
That echo exists on ALL *nix flavored systems - and not just 'on most'.
We'd all save time and headaches.
Specialy the multi-line piping would work right away...
This said, I'd rather try to write/set an $ECHO variable
OOOrr.... I'd simply remove the 3 orientations from the piping, and pretty sure this would help with multi-line pipes.
But thats like the easy way.
Strangley enough, the following produced borked output lines...
shift was required, as the first two lines had only '-' as their output, now, follow up lines miss the first entry, allthough all passed values started with the pipe indicator..
While this enables multi-line pipeing (from grep, cat, etc), it causes an error messages at some math point I need to find first, also no idea where this 'fg %s' comes from...
Well, the echo function didnt quite work as expected:
Any thoughts please?
Thank you

No I mean, seriously... Im confused..
Which is true now?
Might this be the riddles solution?
Does that mean all BASH version have their own builtin echo?
But not all *nix flavors have a 'physical' echo-binary?
In which case, all of this threads would really be solved.
Sometimes you see things you havent all the times before....
i made a lot of processes. here is the code:

I wondered if it was possible to make my input file as variable.
Then I... (1 Reply)
