Hi,
Thanks for the reply. I do not want to print "Done".
I am running a job on a cluster. The output of which remains stored there until I say "getoutput" on my terminal which then brings the output on my hard disk. What I do is I first check the status of the job stored in a file "out" (in my case) and then if the job is done I say "getoutput".
I want to write a shell script which can execute a command "getoutput" (this is a command which is specific to a cluster I am working on) after checking if the job status is "Done".
I have written a line which is trying to do the same:
========================CODE====================
flag[1]=0
flag[2]=0
cat out | gawk 'BEGIN{i=1;}{if($2=="Done") { $flag[i]=1; i=i+1;}'
if($flag[1]==1 && $flag[2]==1); then
getoutput
fi
======================================================
But the problem here is that after the gawk is over, the values of flags are still 0 even if $2=="Done" i.e. gawk is not changing the value of flags globally (only locally) which should get changed if $2=="Done"
Thanks,

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a filename containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
