Generating a generic incremental code
Hi Gurus,
I have several Solaris systems (say system a, system b,system c) which will connect to a windows system (system Z) using SFTP session.
I have a 'txt' file on System Z , which has a simple numeric value on it(say 1) , If I have to increment this number with 1 (1+1 =2) irrespective of the source system . how do i do this.
Ex: I connect from system a to system Z , read the txt file get the number 1 , increment this number to 2 (1+1=2) . When I connect from system b or system c the number in txt file to be read should be 2, this number is once again incremented to 3 (2+1=3).
The Challenge: I'm unable to increment the file using the sftp session.
Please shed some light....
Thanks
Ram.

[ESRCH] if there is no process with a process ID equal to pid.
Note that an implementation may restrict this system call to processes within the same session ID as the calling process.
SEE ALSO
