00:14 2.1Gb 100.0% Searching, 12.4% matched
That's interesting, how the process has managed to rename itself 'searching'. I wonder if it forks every once in a while to tell ps how much farther it's gotten...
No this is not from the ps output, but certainly from the previous command. The ps list follows, and only has got 10 items.
(BTW the process can change its *ARGV[0] string.)
I have not yet seen an indication that usearch directly spawns processes.
If these are spawned by a service-daemon, the strace won't show anything useful.
What gives
?
shortly after running a usearch command?
So far, it is possible that the processes trigger a VM bug in the kernel, and the system runs out of memory without any processes causing it.

In a korn shell script, how can I run several processes in parallel at the same time?
For example, I have 3 processes say p1, p2, p3
if I call them as
p1.ksh
p2.ksh
p3.ksh
they will run after one process finishes. But I want to run them in parallel and want to display "Process p1... (3 Replies)

So, every time I start my computer, I have to run this command

pstree
PSTREE(1) User Commands PSTREE(1)NAME
pstree - display a tree of processes
SYNOPSIS
pstree [-a, --arguments] [-c, --compact] [-h, --highlight-all, -Hpid, --highlight-pid pid] [-g] --show-pgids] [-l, --long]
[-n, --numeric-sort] [-N, --ns-sortns [-p, --show-pids] [-s, --show-parents] [-S, --ns-changes] [-u, --uid-changes] [-Z, --security-con-
text] [-A, --ascii, -G, --vt100, -U, --unicode] [pid, user]
pstree -V, --version
DESCRIPTION
pstree shows running processes as a tree. The tree is rooted at either pid or init if pid is omitted. If a user name is specified, all
process trees rooted at processes owned by that user are shown.
pstree visually merges identical branches by putting them in square brackets and prefixing them with the repetition count, e.g.
init-+-getty
|-getty
|-getty
`-getty
becomes
init---4*[getty]
Child threads of a process are found under the parent process and are shown with the process name in curly braces, e.g.
icecast2---13*[{icecast2}]
If pstree is called as pstree.x11 then it will prompt the user at the end of the line to press return and will not return until that has
happened. This is useful for when pstree is run in a xterminal.
Certain kernel or mount parameters, such as the hidepid option for procfs, will hide information for some processes. In these situations
pstree will attempt to build the tree without this information, showing process names as question marks.
OPTIONS -a Show command line arguments. If the command line of a process is swapped out, that process is shown in parentheses. -a implicitly
disables compaction for processes but not threads.
-A Use ASCII characters to draw the tree.
-c Disable compaction of identical subtrees. By default, subtrees are compacted whenever possible.
-G Use VT100 line drawing characters.
-h Highlight the current process and its ancestors. This is a no-op if the terminal doesn't support highlighting or if neither the
current process nor any of its ancestors are in the subtree being shown.
-H Like -h, but highlight the specified process instead. Unlike with -h, pstree fails when using -H if highlighting is not available.
-g Show PGIDs. Process Group IDs are shown as decimal numbers in parentheses after each process name. -p implicitly disables com-
paction. If both PIDs and PGIDs are displayed then PIDs are shown first.
-l Display long lines. By default, lines are truncated to the display width or 132 if output is sent to a non-tty or if the display
width is unknown.
-n Sort processes with the same ancestor by PID instead of by name. (Numeric sort.)
-N Show individual trees for each namespace of the type specified. The available types are: ipc, mnt, net, pid, user, uts. Regular
users don't have access to other users' processes information, so the output will be limited.
-p Show PIDs. PIDs are shown as decimal numbers in parentheses after each process name. -p implicitly disables compaction.
-s Show parent processes of the specified process.
-S Show namespaces transitions. Like -N, the output is limited when running as a regular user.
-u Show uid transitions. Whenever the uid of a process differs from the uid of its parent, the new uid is shown in parentheses after
the process name.
-U Use UTF-8 (Unicode) line drawing characters. Under Linux 1.1-54 and above, UTF-8 mode is entered on the console with echo -e
' 33%8' and left with echo -e ' 33%@'
-V Display version information.
-Z (SELinux) Show security context for each process. This flag will only work if pstree is compilied with SELinux support.
FILES
/proc location of the proc file system
BUGS
Some character sets may be incompatible with the VT100 characters.
