Sirs,
i am trying to create simple script file..
what i do is grep for a pattern and output 1 line after it.
exmp:
grep -A 1 time files.txt
Output:
time
file1
time
file2
---
Is there some option I can use so I can get on result each 2 lines combined as one file?
like:
time file1
time file2
time file3
Thanks beforehand
you want it to print the word "time" or the actual time of day? (11:09pm) I dont know if grep has an option like that. You might have to combine it with something like awk.
#more file1.txt
this is line 1 red
this is line 2 orange
this is line 3 yellow
this is line 4 green
this is line 5 blue
this is line 6 purple
this is line 7 blue
this is line 8 red
this is line 9 blue
this is line 10 red
So perhaps you want to grep for the lines with "blue" in them. what do you want your output to look like?
example output
#./script
11:20am this is line 5 blue
11:20am this is line 7 blue
11:20am this is line 9 blue
btw I am just writing this reply to see if i got your question correct. I'm sure theres a very elegant way to do this. Your answer will come shortly I'm sure. People here are VERY good!

or perhaps yoru input file already has the times and you are looking for specific times? example
#more file1.txt
11:30am this is line 1
11:30pm this is line 2
11:00am this is line 3
11:00pm this is line 4
11:30am this is line 5
11:40pm this is line 6
11:30am this is line 7
and you want your output to only print the 11:30am lines?
Just trying to be as specific as possible so others can get you exactly the help you need.
