Here's what the log file gives (output with hd): 00000000 1b 5b 31 6d 1b 5b 37 6d 25 1b 5b 32 37 6d 1b 5b |.[1m.[7m%.[27m.[| 00000010 31 6d 1b 5b 6d 20 20 20 20 20 20 20 20 20 20 20 |1m.[m | 00000020 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 | | * 00000060 20 20 20 20 0d 20 0d 0d 1b 5b 6d 1b 5b 32 37 6d | . ...[m.[27m| 00000070 1b 5b 32 34 6d 1b 5b 4a 7a 69 72 61 25 20 1b 5b |.[24m.[Jzira% .[| 00000080 4b 1b 5b 3f 32 30 30 34 68 62 08 62 69 6e 64 6b |K.[?2004hb.bindk| 00000090 65 79 20 2d 65 1b 5b 3f 32 30 30 34 6c 0d 0d 0a |ey -e.[?2004l...| 000000a0 1b 5b 31 6d 1b 5b 37 6d 25 1b 5b 32 37 6d 1b 5b |.[1m.[7m%.[27m.[| 000000b0 31 6d 1b 5b 6d 20 20 20 20 20 20 20 20 20 20 20 |1m.[m | 000000c0 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 | | * 00000100 20 20 20 20 0d 20 0d 0d 1b 5b 6d 1b 5b 32 37 6d | . ...[m.[27m| 00000110 1b 5b 32 34 6d 1b 5b 4a 7a 69 72 61 25 20 1b 5b |.[24m.[Jzira% .[| 00000120 4b 1b 5b 3f 32 30 30 34 68 07 7e |K.[?2004h.~| 0000012b The 07 7e is what the exec-formatted generates (the Ctrl-G doesn't seem to have any effect in zsh).

The shell sees the tilde, as if it were entered with the keyboard. Note that I can replace exec-formatted("browser %s", PRIMARY) by exec-formatted("/bin/true", PRIMARY) and I get the same behavior in xterm, i.e. the command doesn't matter. > > then in the xterm: > > > > zira% bindkey -e > > Perhaps "zira%" is your shell prompt. Yes, the hostname follwed by "%" is the default zsh prompt. > What does "bindkey -e" have to do with exec-formatted? "bindkey -e" selects Emacs editing mode. It just makes the issue visible. But with the "echo '" + Ctrl-V test, the same issue is reproducible without needing "bindkey -e": 00000000 1b 5b 31 6d 1b 5b 37 6d 25 1b 5b 32 37 6d 1b 5b |.[1m.[7m%.[27m.[| 00000010 31 6d 1b 5b 6d 20 20 20 20 20 20 20 20 20 20 20 |1m.[m | 00000020 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 | | * 00000060 20 20 20 20 0d 20 0d 0d 1b 5b 6d 1b 5b 32 37 6d | . ...[m.[27m| 00000070 1b 5b 32 34 6d 1b 5b 4a 7a 69 72 61 25 20 1b 5b |.[24m.[Jzira% .[| 00000080 4b 1b 5b 3f 32 30 30 34 68 65 08 65 63 68 6f 20 |K.[?2004he.echo | 00000090 27 5e 08 1b 5b 37 6d 5e 1b 5b 37 6d 5b 1b 5b 32 |'^..[7m^.[7m[.[2| 000000a0 37 6d 5b 32 30 31 7e |7m[201~| 000000a7 The effect of exec-formatted is what appears after "27 5e 08". -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
