   • Shell Script to Demonstrate Wait Command in Linux

     Wait command is one of the process management commands. There are different process commands in Linux mainly 5 commands are widely used which are ps, wait, sleep, kill, exit.

     ps is an acronym for process status. It displays information about the active processes. wait command will suspend execution of the calling thread until one of its children terminate. It will return the exit status of that command. The sleep command is used to delay the execution of the next command for a given number of seconds, hours, minutes, days. kill is used to terminate a background running process. It sends a terminate signal to the process and then processes halts. It takes process ID as an argument. exit command is used to exit from the current shell environment.

     wait is an inbuilt command in the Linux shell. It waits for the process to change its state i.e. it waits for any running process to complete and returns the exit status.

     Syntax:

     wait [ID]

     Here, ID is a PID (Process Identifier) which is unique for each running process....

     change to

     tail -"$Lines1"f /opt/grinder/svn/IAVS/GrinderLogs/GrinderBaseLogs/Lg2Logs/"$GrinderLg2"-"$c"-data.log>>/opt/grinder/svn/IAVS/GrinderLogs/GrinderBaseLogs/"$GrinderLG1"-"$c"-data.log-

     should work.

     In my setup i have tested as below way

     #!/bin/sh`"tail -10f filename"`-

     give error filename not found

     But

     #!/bin/shtail -10f filename-

     This works fine.
