I'm new to mac and everything around, I just want to know if I can code a sort of plug-in to show the batterie of the magic mouse, in the menu bar.
What is the type of template i have to choose in Xcode to realize my idea.
So this answer is more a shell-first answer, but you can execute shell commands in ObjectiveC/Swift too.
You can get the percentage of your bluetooth devices pretty easy with this shell command:
ioreg -l | grep BatteryPercent
With a little bit of regex you should be able to get the number:
Regex 1: https://regexr.com/3ouu3
Regex 2: https://regexr.com/3ouu6
Or as a complete shell solution:
ioreg -c BNBMouseDevice |grep '"BatteryPercent" =' | tr -dc '0-9'
And the same for the Magic Keyboard:
ioreg -c AppleBluetoothHIDKeyboard |grep '"BatteryPercent" =' | tr -dc '0-9'
So know I have differents informations I would like to know to insert the BatteryPercent from the IORegistery explorator in my code ;)
I have the Bundle Identifier from IORegistery :com.apple.driver.AppleBluetoothMultitouch

I am trying to get the meta title of some website...
some people write title like
`<title>AllHeart Web INC, IT Services Digital Solutions Technology
</title>
`
`<title>AllHeart Web INC, IT Services Digital Solutions Technology</title>`
`<title>
AllHeart Web INC, IT Services Digital Solutions Technology
</title>`
some like more ways... my current focus on above 3 ways...
I wrote a simple code, it only capture 2nd way of title written, but i am not sure how can I grep the other ways,
`curl -s https://allheartweb.com/ | grep -o '<title>.*</title>'`
I also made a code (very bad i guess)
where i can grep number of line like
`
% curl -s https://allheartweb.com/ | grep -n '<title>'
7:<title>AllHeart Web INC, IT Services Digital Solutions Technology
% curl -s https://allheartweb.com/ | grep -n '</title>'
8:</title>
`
and store it and run loop to get title item... which i guess a bad idea...
any help I can get all possible of getting title?
Try this:
curl -s https://allheartweb.com/ | tr -d '\n' | grep -m 1 -oP '(?<=<title>).+?(?=</title>)'
You can remove newlines from HTML via tr because they have no meaning in the title. The next step returns the first match of the shortest string enclosed in <title> </title>.
This is quite a simple approach of course. xmllint would be better but that's not available to all platforms by default.
'grep' is not a very good tool to match multiple lines. It is processing line-by-line. You could hack that by making your incoming text one line like
curl -s https://allheartweb.com/ | xargs | grep -o -E "<title>.*</title>"
This is probably what you want.
Try this sed:
curl -s https://allheartweb.com/ | sed -n "{/<title>/,/<\/title>/p}"
I am looking at this question: https://leetcode.com/problems/valid-phone-numbers/
which asked using a cmd to extract the phone numbers.
I found this command works:
cat file.txt | grep -Eo '^(\([0-9]{3}\) ){1}[0-9]{3}-[0-9]{4}$|^([0-9]{3}-){2}[0-9]{4}$'
while this failed:
cat file.txt | grep -E '(^(\([0-9]{3}\))|^([0-9]{3}-))[0-9]{3}-[0-9]{4}'
I don't know why the second failed. Does it because grep doesn't support OR in a group?
No, it's because you dropped the space, so space in a phone number will no longer be allowed.
Also, the grouping in your regex seems to be off by a whack or two. What are you actually trying to express?
Finally, you have a useless use of cat -- grep can perfectly well read one or more input files without the help of cat.
Does anyone know of any possible way to determine or glean this information from the terminal (in order to use in a bash shell script)?
On my Macbook Air, via the GUI I can go to "About this mac" > "Displays" and it tells me:
Built-in Display, 13-inch (1440 x 900)
I can get the screen resolution from the system_profiler command, but not the "13-inch" bit.
I've also tried with ioreg without success. Calculating the screen size from the resolution is not accurate, as this can be changed by the user.
Has anyone managed to achieve this?
I think you could only get the display model-name which holds a reference to the size:
ioreg -lw0 | grep "IODisplayEDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6 | grep '^LSN\|^LP'
will output something like:
LP154WT1-SJE1
which depends on the display manufacturer. But as you can see the first three numbers in this model name string imply the display-size: 154 == 15.4''
EDIT
Found a neat solution but it requires an internet connection:
curl -s http://support-sp.apple.com/sp/product?cc=`system_profiler SPHardwareDataType | awk '/Serial/ {print $4}' | cut -c 9-` |
sed 's|.*<configCode>\(.*\)</configCode>.*|\1|'
hope that helps
The next script:
model=$(system_profiler SPHardwareDataType | \
/usr/bin/perl -MLWP::Simple -MXML::Simple -lane '$c=substr($F[3],8)if/Serial/}{
print XMLin(get(q{http://support-sp.apple.com/sp/product?cc=}.$c))->{configCode}')
echo "$model"
will print for example:
MacBook Pro (13-inch, Mid 2010)
Or the same without perl but more command forking:
model=$(curl -s http://support-sp.apple.com/sp/product?cc=$(system_profiler SPHardwareDataType | sed -n '/Serial/s/.*: \(........\)\(.*\)$/\2/p')|sed 's:.*<configCode>\(.*\)</configCode>.*:\1:')
echo "$model"
It is fetched online from apple site by serial number, so you need internet connection.
I've found that there seem to be several different Apple URLs for checking this info. Some of them seem to work for some serial numbers, and others for other machines.
e.g:
https://selfsolve.apple.com/wcResults.do?sn=$Serial&Continue=Continue&num=0
https://selfsolve.apple.com/RegisterProduct.do?productRegister=Y&country=USA&id=$Serial
http://support-sp.apple.com/sp/product?cc=$serial (last 4 digits)
https://selfsolve.apple.com/agreementWarrantyDynamic.do
However, the first two URLs are the ones that seem to work for me. Maybe it's because the machines I'm looking up are in the UK and not the US, or maybe it's due to their age?
Anyway, due to not having much luck with curl on the command line (The Apple sites redirect, sometimes several times to alternative URLs, and the -L option doesn't seem to help), my solution was to bosh together a (rather messy) PHP script that uses PHP cURL to check the serials against both URLs, and then does some regex trickery to report the info I need.
Once on my web server, I can now curl it from the terminal command line and it's bringing back decent results 100% of the time.
I'm a PHP novice so I won't embarrass myself by posting the script up in it's current state, but if anyone's interested I'd be happy to tidy it up and share it on here (though admittedly it's a rather long winded solution to what should be a very simple query).
This info really should be simply made available in system_profiler. As it's available through System Information.app, I can't see a reason why not.
Hi there for my bash script , under GNU/Linux : I make the follow to save
# Resolution Fix
echo `xrandr --current | grep current | awk '{print $8}'` >> /tmp/width
echo `xrandr --current | grep current | awk '{print $10}'` >> /tmp/height
cat /tmp/height | sed -i 's/,//g' /tmp/height
WIDTH=$(cat /tmp/width)
HEIGHT=$(cat /tmp/height)
rm /tmp/width /tmp/height
echo "$WIDTH"'x'"$HEIGHT" >> /tmp/Resolution
Resolution=$(cat /tmp/Resolution)
rm /tmp/Resolution
# Resolution Fix
and the follow in the same script for restore after exit from some app / game
in some S.O
This its execute command directly
ResolutionRestore=$(xrandr -s $Resolution)
But if dont execute call the variable with this to execute the varible content
$($ResolutionRestore)
And the another way you can try its with the follow for example
RESOLUTION=$(xdpyinfo | grep -i dimensions: | sed 's/[^0-9]*pixels.*(.*).*//' | sed 's/[^0-9x]*//')
VRES=$(echo $RESOLUTION | sed 's/.*x//')
HRES=$(echo $RESOLUTION | sed 's/x.*//')
I want to ask you If anybody know a simple way to access Mouse and Keyboard battery state in Mac OS. There are some API to access this information? Thanks!
For the Keyboard it is:
ioreg -n "IOAppleBluetoothHIDDriver" | grep -i "batterypercent" | sed 's/[^[:digit:]]//g'
and for the Magic Mouse it is:
ioreg -n "BNBMouseDevice" | grep -i "batterypercent" | sed 's/[^[:digit:]]//g'
I have very little experience with AWK, but it seems like the best tool for my purpose now.
I am trying to get a list of nearby BSSIDs by using the airport -s command in OS X. Output looks like this:
SSID BSSID RSSI CHANNEL HT CC SECURITY (auth/unicast/group)
MyWireless 00:11:22:33:44:55 -85 64 N US WPA(PSK/TKIP/TKIP) WPA2(PSK/TKIP/TKIP)
Your Wireless 66:77:88:99:00:11 -84 64 N US WPA(PSK/TKIP/TKIP) WPA2(PSK/AES/TKIP)
So clearly I'm looking for the second column. So I tried:
airport -s | awk '{print $2}'
And that works fine until I have an SSID with a space in its name. I've tried setting IFS to tab, FS to tab, nothing really seems to work.
I keep getting this:
00:11:22:33:44:55
Your
I am hoping eventually to get a simple list:
00:11:22:33:44:55
66:77:88:99:00:11
I know this is a one-line solution, so I'm really embarrassed that I even have to ask... Please be kind. :)
Seems like a regexp might be better suited. Maybe just a simple egrep -o
airport -s | egrep -o '([[:xdigit:]]{2}:){5}[[:xdigit:]]{2}'
I'd be curious to see how you are setting FS to tab, because that ought to work if airport is outputting a tab between columns.
You can also use a regular expression as a field separator (at least in gawk). This will handle the case when there is one or more tabs between fields:
airport -s | awk -F'\t+' '{print $2}'
easy, you just have to go through each field and check for the pattern
airport -s | awk 'NR>1{ for(i=1;i<=NF;i++){if($i~/^[0-9][0-9]:/){print $i}}}'
