I could not manage to do this via the call itself (in the Android Shell).
I just read through all files and write them to one Log file.
This solution slows the whole process down, but was the only solution I found.
Get the output of multiple strace calls in one file
题
I want to get the Output of multiple strace calls in one file,
but i do not know how.
At the moment i am using:
strace -o tmpfile, but this just puts the output of one file in and then overrites the file with the new output.
Has anyone an idea, how to do this? I hope this is no dumb question.
Thanks in advance.

Under the bash shell use the following command
strace -o >(cat >>outputfile) command [args] ...
This will pass to the -o flag an argument that will appear like a file, but will be instead a file descriptor to the standard input of the
cat >>outputfile
process. This process will append its input to the specified output file.
Instead of strace -o somefile command
, can you just do strace command >> somefile
? Alternatively, assuming a similar version of strace
, my manual for strace
indicates this should work: strace -o "|tail -a somefile" command
(the -o "|command"
functionality is implemented by strace
itself, not by the shell).
The strace output is on stderr, strace 2>> outfile
did the trick for me. If you invoke strace as single command you have to call it like this: adb -e shell "strace -p pid 2>> file"
