grep ALL.TXT -a ZV8L | grep -a PY1ZRJ
grep: ZV8L: No such file or directory

man grep:
grep [OPTIONS] PATTERN [FILE...]

So:

grep -a ZV8L ALL.TXT  | grep -a PY1ZRJ

Hi again William!

Please, be so kind to accept my apologies but you are extremely right!

Using the -a switch has pemitted grep tp show the pattern correctly!

marco@localhost:~/.local/share/WSJT-X> cat ALL.TXT |grep -a ZV8L|grep -a PY1ZRJ

220218_150746    24.915 Tx FT8      0  0.0 1964 ZV8L PY1ZRJ GG87

220218_150845    24.915 Tx FT8      0  0.0 1964 ZV8L PY1ZRJ R+05
220218_150900    24.915 Rx FT8      8  0.2 1470 PY1ZRJ ZV8L RRR
220218_150915    24.915 Tx FT8      0  0.0 1964 ZV8L PY1ZRJ 73
220218_150930    24.915 Rx FT8     10  0.2 1469 PY1ZRJ ZV8L 73

And more important that the above, this one:

marco@localhost:~/.local/share/WSJT-X> cat ALL.TXT |grep -a 3X2021|grep -a PY1ZRJ|grep RR73

*220218_181600    21.080 Rx FT8 -12  0.2  754 <PY1ZRJ> 3X2021 RR73**
**220218_183200    21.080 Rx FT8    -12  0.2  764 <PY1ZRJ> 3X2021 RR73*

Probably my bash history is causing that issue but it doesn't contains any data inside, just text.

Great suggestion! Thanks again William!!!

Best regards!

Marco

Hi William!

This is not a matter of UNIX command syntax, the fact is that such string is not present in the file.

Thanks and regards,

Marco, PY1ZRJ
