Code:

awk '!/Not/ && /Ok to Proceed/ && NR==15{print "" > "Go.txt"}' file

the above code means:-
if the row does not contain "NOT" && contain "Ok to Proceed" && the row number ==15 then do
print "nothing" and send it to "GO.txt" file

and the file path is the current path.

What about using fgrep or -F flag?
Maybe something like this... If the fixed string "Not ok to proceed" is not found in the file, then just check if "ok to Proceed" exists; if it does, then generate the output.

Code:

if [[ `grep -Fi "Not ok to Proceed" ./a.txt` -ne 0 ]]
   then  
   if [[ `grep -ic "ok to Proceed"` ]]
   then
        touch go.txt
   fi  
fi

Try with fgrep instead of grep -F if it doesn't work properly.

Thanks for all of ur responses
Its working with grep.

I have one more question on this, suppose if i want to go and check the text file based on line no For example, I need to go to the line 15 in text file and then check for the String "OK to Proceed" or "Not ok to Proceed" because
my text file will contain a comment on 10th line with "Not Ok to Proceed"

So either i need to go based on line number or need to check for the second occurence of the "Not Ok to Proceed"

Please advice

Thanks in Advance,
Sandeep

You can do various things, such as:

1. Strip the comment, and pipe only appropriate input to grep as

Code:

sed 's/^#//' | grep '<PATTERN>'

2. Extract part of file, using tail or head as:
tail -n +11 FILE | grep '<PATTERN>'

3. or search for 2nd occurrence and so on.

Select an appropriate way, by analyzing your data.

Not clear

Code:

awk '!/Not/ && /Ok to Proceed/ && NR==15{print "" > "Go.txt"}' file

Code:

#!/bin/bash  -v
grep "OK to proceed" check.txt
if [ $? -eq 0 ]
then
 touch "Ok.txt"
fi

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.
