Executing pidcat.py on Ubuntu 18.04.4 LTS results:

/usr/bin/env: invalid option -- 'S'
Try '/usr/bin/env --help' for more information.

Shebang was changed in https://github.com/JakeWharton/pidcat/commit/e5fa59974b312727c503e42b1bf94e1ecf3e556d after changing it back to #!/usr/bin/python -u it starts to work again.

I have env (GNU coreutils) 8.28 installed. Should be the default from Ubuntu. Looking in env --help doesn't list the -S at all, only the following:

Usage: env [OPTION]... [-] [NAME=VALUE]... [COMMAND [ARG]...]
Set each NAME to VALUE in the environment and run COMMAND.

Mandatory arguments to long options are mandatory for short options too.
  -i, --ignore-environment  start with an empty environment
  -0, --null           end each output line with NUL, not newline
  -u, --unset=NAME     remove variable from the environment
  -C, --chdir=DIR      change working directory to DIR
      --help     display this help and exit
      --version  output version information and exit

A mere - implies -i.  If no COMMAND, print the resulting environment.

This specifically handles the case where you get a log snippet that may not have any pid creation lines in it and pidcat ends up filtering everything out. In this case we just print the line if we haven't seen any pids yet.

An alternative would be allowing filter by pid, however I find grep works fine for that.

On the M preview 1, with a Nexus 6: Alas more changes :| It seems to use the same "Start proc" format as 5.1, but the (default) columns have changed.

An example log line: 06-06 12:14:46.355 372 18641 D audio_hw_primary: disable_audio_route: reset and update mixer path: audio-record

Regex + group changes that fix output: LOG_LINE = re.compile(r'^\S+\s\S+\s+(\d+)\s+\S+\s([A-Z])\s([^:]+)\s(.+)$') owner, level, tag, message = log_line.groups()

Not sure how you'd like to fit them in with the existing code (if you have any intention of fixing this for preview releases), but I figured I'd at least try to save some effort :)

I added this code before I found the "--always-display-tags" switch which allows for useful grepping. I don't know if it's useful, but thought I would pass it along anyways.

Enabled with the --timestamp flag. Fixes #9.

All I've done is rebase @marczych's commit in PR #34 to the latest master. I've also removed the short -t flag because it's already being used for tags. Let me know if any other changes are required to get this merged in.

Hey Jake,

I'm on a macbook pro, python installed. I installed pidcat via brew, everything seemed to work fine. But when I want to launch pidcat, I have this error (OSError: [Errno 2] No such file or directory).

I'm not sure if it's something from pidcat or my computer. I asked Google but it couldn't give any good answer.... so...

Do you have any idea ?

Hey,

I wanted to filter dalvikvm logs from pidcat output. So, it would be nice to have an option to always display tagname, so that we can pipe its output to grep and filter certain tags.

./pidcat.py -l D  --always-display-tags com.trhura.android.somepackage | grep -v -e "dalvikvm"

Right now piping to non-screen sources are not supported since they would fail when try to get the width of a terminal. This adds the flexibility to add a terminal_width parameter so that we don't have to determine the width and trigger the IOError.

Running on OS X 10.11.1 in iTerm2 connected to a Nexus 6P

Issue: pidcat doesn't output anything

STR:

• Connect 6P
• Run pidcat

Interesting things to note (maybe):

• adb logcat does have expected output
• when I disconnect my device after starting pidcat, the pidcat process automatically stops. It seems to recognize there's a device attached.
• adb devices shows that the device is recognized

Add support for an alternative log format for starting new processes. Also reverts the "print line if we have not seen any pids" diff, which it sounds like was motivated by this flaw? Either way that change is fairly harmful to what I believe is normal use of pidcat.

Every now and then it seems that adb spits out a line that pidcat chokes on:

dalvikvm  D  Trying to load lib /data/app-lib/com.motorola.aon-1/libpartial_display.so 0x41fbba88

I'm running on Bash 5.1.16 and have the TERM variables set appropriately:

$ env | grep TERM
COLORTERM=truecolor
TERM=xterm-256color

If I run pidcat with python3, I get output like this:

b'\x1b[37m        ActivityManager\x1b[0m \x1b[30;102m I \x1b[0m Process com.samsung.android.app.galaxyfinder:appservice (pid 18912) has died: fg  SVC (127,1420)'

but if I run with python2, then I get colorized output as expected.

If I delete the .encode(utf-8) from the final print statement, then it works as expected on both Python2 and Python3, but I suspect this might cause problems on some systems if locale isn't utf-8.

I'm not getting autocompletion for package names with Android 12 emulator.

The reason is that this command fails:

adb $device_selected shell ls /data/data 2>/dev/null

because of a permissions issue:

adb shell ls /data/data
ls: /data/data: Permission denied

This replacement works fine for me:

local apks=$(adb $device_selected shell pm list packages 2>/dev/null | sed "s/package://g" | tr '\n' ' ' | tr -d '\r')

Hey!

First off, thank you for the great util, Jake. And all the other cool stuff you've built througout the years.

I'm having an issue where pidcat, installed from brew, can no longer run on macOS 12.3. I believe this is because of Python 2 having been removed on this version of macOS.

I'm getting the following output, when attempting to run pidcat:

~ pidcat
zsh: /opt/homebrew/bin/pidcat: bad interpreter: /usr/bin/python: no such file or directory

This in turn is caused by https://github.com/JakeWharton/pidcat/blob/44b4a106bb25776cbb551044b303520a07a51c1e/pidcat.py#L1:

#!/usr/bin/python -u

On macOS 12.3, /usr/bin/python does not exist - only /usr/bin/python3.

Running on the latest development version (as listed in the current README.md, does not solve the issue, as it still looks for python, which still does not exist.

One alternative that could resolve the issue would be to update pidcat to explicitly try to use python3, but this would have some less desirable backwards compatibility issues, perhaps.

The README.md suggests the following to be added to the shell config to enable pidcat:

export PATH=$PATH:<path to Android SDK>/platform-tools
export PATH=$PATH:<path to Android SDK>/tools

This step is unnecessary for machines that have the ANDROID_SDK_ROOT environment variable set up in the shell config for Flutter developers. We can modify the documentation to account for this since Android Studio also supports Flutter development.
