Hi All ,

My colegue using this command and i doesnt understand what it does.

ps -ef | grep pm

pm is may be powermart .

i dont know what is ps and -ef flag does.

If i want to serch for all the directories listed with .parm extention how can i search for all the directory using grep command?

Thanks to All in advance,

ps -ef
ps - see the man page for ps
ps = report process status
ps -e list info about every process now running
ps -f generate a full listing

So he is checking all processes and then looking for those that have 'pm' in them.

Use the find command, not the grep command - or you can use a ls -Ra and pipe to grep but the find command would be easier.

ls -l | grep ^d

gives all direcries under current directory.

man ps for other question.

1307102 - Process ID
843936 --- Parent Process ID
0 --- Processor utilization for scheduling
0.54 --- The cumulative execution time for the process.

I do n't think grep is suitable command in this context.

Use 'find' command instead.

find $dir -name "*param"

will give all .param files under $dir.

or write a shell script and pass dir as commnad line argument and in hte script
do some thing like this

find $1 -name "*.param"

Hi bhargav,

as you told this command what is -name , and $dir i have to specify directory path or just write $dir.sorry i am begginer so dont know much about it.

find $dir -name "*param"

THanks

specify dirpath in place of $dir for find command.

or put

dir=/path/of/the/dir

and user $dir as shell variable.

There are lot of unix tutorials in the FAQ area of this web site
to make start ...
