grep command in Solaris

grep with ls command:
======================

• Finding files whose last 4 digits are not integer:

bash-3.2# ls -ltr *[!0-9][!0-9][!0-9][!0-9]
-rw-r--r--   1 root     root     8101353 May 21  2012 apache-tomcat-7.0.27.zip

-r--------   1 root     root          16 May  6 15:01 autoreg_key
-rw-------   1 root     root          72 May  6 15:01 autoreg_config
-rw-r--r--   1 oracle   oinstall       0 May 11 13:25 DGStatusMonitor.lock

• Finding files whose last 4 digits are integer:

bash-3.2# ls -ltr *[0-9][0-9][0-9][0-9]

• Finding only directories:

bash-3.2# ls -ltr | grep ^d

• Finding all files whose file name starts with first two digits capital alphabet, then 3rd, 4th digit are numeric.

bash-3.2# ls [A-Z][A-Z][0-9][0-9]*

grep command:
==============

• Finding all files in a directory having string "running":

bash-3.2# grep -l running *
dg_status_Sat_May_11_13:25:40_2013.log
bash-3.2# 

• Finding lines in file dg_status_sasa.log where "running" string is present.

bash-3.2# grep running dg_status_sasa.log 
-- dgstatusmonitor running at Sun_May_12_01:29:47_2013 --
-- dgstatusmonitor running at Sun_May_12_13:29:55_2013 --
-- dgstatusmonitor running at Mon_May_20_01:35:45_2013 --
-- dgstatusmonitor running at Mon_May_20_13:35:53_2013 --
-- dgstatusmonitor running at Tue_May_21_01:36:01_2013 --
-- dgstatusmonitor running at Tue_May_21_13:36:09_2013 --
bash-3.2# 

• Finding lines in file dg_status_sasa.log where "running" string is not present.

bash-3.2# grep -v running dg_status_sasa.log 

• Check for case insensitive "running" sting also:

bash-3.2# grep -i running dg_status_sasa.log 

• Checking how many times "running" occured:

bash-3.2# grep -c running saasaa.log 
6

• Check for line number at which it occurs:

bash-3.2# grep -n running saasaa.log 
5:-- dgstatusmonitor running at Sun_May_12_01:29:47_2013 --
7:-- dgstatusmonitor running at Sun_May_12_13:29:55_2013 -- running
21:running
50:-- dgstatusmonitor running at Mon_May_20_01:35:45_2013 --
52:-- dgstatusmonitor running at Mon_May_20_13:35:53_2013 --
54:-- dgstatusmonitor running at Tue_May_21_01:36:01_2013 --
56:-- dgstatusmonitor running at Tue_May_21_13:36:09_2013 --

• Make a search for two patterns using extended grep (egrep):

bash-3.2# egrep '(running|DGMGRL)' saasaa.log 
-- dgstatusmonitor running at Sun_May_12_01:29:47_2013 --
-- dgstatusmonitor running at Sun_May_12_13:29:55_2013 -- 
running
