Concatenating two log files 2

[ddrillich]

Good Day,

I have these dynamically generated log files, except the most recent one - index.log. How can I concatenate the last renamed one (in this case index.log.19-Mar-10-19.44.57) with index.log.

[autonomy@sbkj2ksrchdihp01 logs]$ \ls -ltr ind*
-rw-r--r-- 1 autonomy text 1048592 Mar 17 00:06 index.log.17-Mar-10-00.06.21
-rw-r--r-- 1 autonomy text 1048596 Mar 17 00:07 index.log.17-Mar-10-00.07.48

Much appreciated.

You can use the concatenate command:

cat index.log.19-Mar-10-19.44.57 index.log > /tmp/concatenated.log

Or were you looking for a way to do this automatically regardless of the filename...?

[ddrillich]

Thank you Annihilannic,

Right, I do need to do this automatically regardless of the filename...

cat $(ls -tr ind* | tail -2)

[ddrillich]

Magnificent as usual.

Thanks,

Hurrah, a LUOC rather than an UUOC!!

The internet - allowing those who don't know what they're talking about to have their say.

 

[ddrillich]

Ok, UUOC stands for Useless Use of Cat. What is LUOC?

I'm guessing "Legitimate".

Quite right, Annihilannic!
