so i have a very long script which i have to run. when i run this script, i want to monitor the the openssl commands it runs.
the way ive attempted to do this is:
Code:
watch -t -n 1 "(date '+TIME:%H:%M:%S' ; ps aux | egrep openssl | egrep -v grep)" 2>&1 | tee -a logfile
the above command is suppose to run the watch command continuously looking for the word "openssl" in the process table.
when it finds any process that has the word, its suppose to copy the entire line from the process table containing the "openssl" command and then log it to a file called logfile.
however, this isnt working as expected. when i view the logfile all i see is a bunch of empty lines and blank spaces and these weird characters:
On Linux I could use the `watch` command to loop a command X times. Is there a similar command on AIX? If not, is there a way to write a loop on the command line to do this?
Linux: watch -d -n 60 'db2 list applications show detail | grep Connect | wc -l'
AIX: ??? (2 Replies)
Hi Experts,,

Hi there,
I was wondering if there was a way in UNIX that I could set up a running script that monitors a certain folder (and all the folders and files contained within it) so that if any file changes then it will be the change logged within a log file. I dont know if this is possible in Unix... (6 Replies)
Hi all,
I am trying to create a file that shows the CPU usage, constantly updating (similar to TOP).
So far i have a file (called test) containing:
echo "The current CPU usage is:" `ps -e -o pcpu|awk 'NR > 0 { s +=$1 }; END {print s"%"}'`
and then I ran the command:
watch -d 0.5 -t... (3 Replies)
Hi,
Please help me out!
In the man pages they dont talk about any options that can be used to terminate a running 'watch' command. Do you know a way of terminating the command using an option?
Thanks (1 Reply)
watch is a common linux command that executes a program periodically, showing output fullscreen.
I couldn't find anything for hpux, so I created the following shell which the user is testing:
cat /usr/bin/watch
#!/bin/sh
while ; do
clear
echo "Command: $*"
date
echo ""

NPM-RUN-SCRIPT(1)NPM-RUN-SCRIPT(1)NAME
npm-run-script - Run arbitrary package scripts
SYNOPSIS
npm run-script <command> [--silent] [-- <args>...]
alias: npm run
DESCRIPTION
This runs an arbitrary command from a package's "scripts" object. If no "command" is provided, it will list the available scripts.
run[-script] is used by the test, start, restart, and stop commands, but can be called directly, as well. When the scripts in the package
are printed out, they're separated into lifecycle (test, start, restart) and directly-run scripts.
As of ` https://blog.npmjs.org/post/98131109725/npm-2-0-0, you can use custom arguments when executing scripts. The special option -- is
used by getopt https://goo.gl/KxMmtG to delimit the end of the options. npm will pass all the arguments after the -- directly to your
script:
npm run test -- --grep="pattern"
The arguments will only be passed to the script specified after npm run and not to any pre or post script.
The env script is a special built-in command that can be used to list environment variables that will be available to the script at run-
time. If an "env" command is defined in your package, it will take precedence over the built-in.
In addition to the shell's pre-existing PATH, npm run adds node_modules/.bin to the PATH provided to scripts. Any binaries provided by
locally-installed dependencies can be used without the node_modules/.bin prefix. For example, if there is a devDependency on tap in your
package, you should write:
"scripts": {"test": "tap test/*.js"}
instead of
"scripts": {"test": "node_modules/.bin/tap test/*.js"}
to run your tests.
The actual shell your script is run within is platform dependent. By default, on Unix-like systems it is the /bin/sh command, on Windows it
is the cmd.exe. The actual shell referred to by /bin/sh also depends on the system. As of `
https://github.com/npm/npm/releases/tag/v5.1.0 you can customize the shell with the script-shell configuration.
Scripts are run from the root of the module, regardless of what your current working directory is when you call npm run. If you want your
script to use different behavior based on what subdirectory you're in, you can use the INIT_CWD environment variable, which holds the full
path you were in when you ran npm run.
npm run sets the NODE environment variable to the node executable with which npm is executed. Also, if the --scripts-prepend-node-path is
passed, the directory within which node resides is added to the PATH. If --scripts-prepend-node-path=auto is passed (which has been the
default in npm v3), this is only performed when that node executable is not found in the PATH.
If you try to run a script without having a node_modules directory and it fails, you will be given a warning to run npm install, just in
case you've forgotten.
You can use the --silent flag to prevent showing npm ERR! output on error.
You can use the --if-present flag to avoid exiting with a non-zero exit code when the script is undefined. This lets you run potentially
undefined scripts without breaking the execution chain.
