Privacy policy: This program will not transfer any information to other networked systems unless specifically requested by the user or the person installing or operating it. For example, the SFTP plugin only connects to the servers the user opens files from.
Line numbers start at 1, as in Go to Line. Supply the option once, with an integer
from 1 through 2147483647 and exactly one log file. Sessions (.lxj) and Session
Files (.lxp) are not supported with this option. Missing, invalid, repeated, or
out-of-range values produce a command-line error before files are opened.
LogExpert waits for normal loading and Session File restoration, then selects and
reveals the requested line with follow-tail disabled. A number beyond the end
selects the last line; an empty file keeps an empty selection. The same behavior
applies when forwarding to an existing instance: the existing routing preferences
choose the window, and an already-open log is reused. While it loads, the latest
line request wins. Navigation is applied once, so later reloads do not repeat it.
This option uses the loaded log's line numbering, including any preprocessing or
combined rollover view. It does not load only part of a large file or map physical
file lines. Rotation, truncation, or other edits can make an external tool's line
number stale. Commands without --line / -n keep their existing behavior.
CI
This is a continous integration build. So always the latest and greates changes. It should be stable but no promises. Can be viewed as Beta.
