.TH PULSEVIEW 1 "June 6, 2017"
.SH "NAME"
PulseView \- Qt-based LA/scope/MSO GUI for sigrok
.SH "SYNOPSIS"
.B pulseview \fR[\fBOPTIONS\fR] [\fBFILE\fR]
.SH "DESCRIPTION"
.B PulseView
is a cross-platform Qt-based GUI for the
.B sigrok
software suite for test and measurement equipment such as logic analyzers,
oscilloscopes, MSOs, and more.
.SH "OPTIONS"
.B PulseView
has very few command line options, as most configuration elements are
available from the GUI itself.
.sp
If the optional \fBFILE\fR argument is supplied, PulseView tries to open
the specified file. It has to be in the "libsigrok session" format (.sr)
unless -I is used to specify the input file format.
.TP
.B "\-l, \-\-loglevel"
Set the libsigrok and libsigrokdecode loglevel. At the moment PulseView
doesn't support setting the two loglevels independently. The higher the
number, the more debug output will be printed. Valid loglevels are:
.sp
\fB0\fP   None
.br
\fB1\fP   Error
.br
\fB2\fP   Warnings
.br
\fB3\fP   Informational
.br
\fB4\fP   Debug

.TP
.B "\-V, \-\-version"
Show version information and exit.
.TP
.BR "\-i, \-\-input\-file " <filename>
Load input from a file. If the
.B \-\-input\-format
option is not supplied, PulseView attempts to load the file as a sigrok session
file.
.TP
.BR "\-I, \-\-input\-format " <format>
Specifies the format of the input file to be loaded.
.TP

command line instead of restoring all previously used sessions as well.
