Redirecting LhA output

Krashan · 24 January 2024, 09:23

I'm writing an Installer script. In this script I need to unpack many files from an LhA archive. Not a problem with Installer

run

statement. Works fine.

However on 68020 @ 28 MHz machine this unpacking takes about a minute. During this time Installer just shows busy pointer and has its UI disabled. Would be nice to display LhA output in a console window, so the user knows what is going on.

To my surprise, plain redirection does not work. For example:

Code:

LhA x somearchive.lha RAM: >CON:////Depacking/AUTO/CLOSE/WAIT

just opens a console window, then nothing, furthermore LhA seems to hang.

Tried with LhA 2.2.

Often times, informational output is printed to stderr, so maybe you need to redirect that

Seems like it is a problem of this particular version of LhA. Works as expected with 2.15.

You may try the lha option "-D" Alternate progress display.

With LhA 2.2 it does not help. LhA 2.15 is OK with or without -D. I have also tested -Qa (simplified console I/O), with the same result. My conclusion is, LhA 2.2 is broken in this regard.

Yes, seems it was fixed in later version: http://aminet.net/package/util/arc/lha_68k
