Perhaps you could try using "strace", eg:
plink -ssh -pw <password> <machine IP>:/ "path"; strace -s 8192 -v -f -o /tmp/trace.log ./daemon

strace should give you an idea of what may be going wrong (logged into /tmp/trace.log)

Unix popularized the hierarchical file system with arbitrarily nested subdirectories, originally introduced by Multics.

Daemon process

I wish to make a process run in the background, but only one instance of it, and not many, so when the program is loaded, it has to check whether another instance of the same program is running and if so to exit. How do I do this ? (4 Replies)

strace-log-merge - merge strace -ff -tt output SYNOPSIS
strace-log-merge STRACE_LOG strace-log-merge --help DESCRIPTION
strace-log-merge merges the output of strace -ff -tt[t] command, prepending PID to each line and sorting the result using time stamp as a key. OPTIONS
--help Show program usage and exit. STRACE_LOG Output file name prefix of files produced by a strace -ff -tt[t] command. EXIT STATUS
0 Success Non-zero Error occurred: either no argument specified (in that case a usage is printed), or something went wrong during the processing of STRACE_LOG.* files. USAGE EXAMPLE
$ strace -o sleepy -ff -tt -e trace=execve,nanosleep sh -c 'sleep 0.1 & sleep 0.2 & sleep 0.3' $ strace-log-merge sleepy | fold -w 72 -s 13475 21:13:52.040837 execve("/bin/sh", ["sh", "-c", "sleep 0.1 & sleep 0.2 & sleep 0."...], 0x7ffde54b2450 /* 33 vars */) = 0 13478 21:13:52.044050 execve("/bin/sleep", ["sleep", "0.3"], 0x5631be4f87a8 /* 33 vars */) = 0 13476 21:13:52.044269 execve("/bin/sleep", ["sleep", "0.1"], 0x5631be4f87a8 /* 33 vars */) = 0 13477 21:13:52.044389 execve("/bin/sleep", ["sleep", "0.2"], 0x5631be4f87a8 /* 33 vars */) = 0 13478 21:13:52.046207 nanosleep({tv_sec=0, tv_nsec=300000000}, NULL) = 0 13476 21:13:52.046303 nanosleep({tv_sec=0, tv_nsec=100000000}, NULL) = 0 13477 21:13:52.046318 nanosleep({tv_sec=0, tv_nsec=200000000}, NULL) = 0 13476 21:13:52.146852 +++ exited with 0 +++ 13475 21:13:52.146942 --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=13476, si_uid=1000, si_status=0, si_utime=0, si_stime=0} --- 13477 21:13:52.247782 +++ exited with 0 +++ 13475 21:13:52.247885 --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=13477, si_uid=1000, si_status=0, si_utime=0, si_stime=0} --- 13478 21:13:52.347680 +++ exited with 0 +++ 13475 21:13:52.347786 --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=13478, si_uid=1000, si_status=0, si_utime=0, si_stime=0} --- 13475 21:13:52.348069 +++ exited with 0 +++ NOTES
strace-log-merge does not work well with strace logs generated by strace -tt invocation that pass midnight, as those lack the information required for the proper sorting. Employing the -ttt option in the respective strace invocation should solve the problem. BUGS
strace-log-merge does not perform any checks whether the files specified are in the correct format and implies that only files from a sin- gle strace session match STRACE_LOG.* glob pattern. HISTORY
The initial version of strace-log-merge was written by Denys Vlasenko in 2012. REPORTING BUGS
Problems with strace-log-merge should be reported to the strace mailing list at <>. SEE ALSO
