tail command

[Simon R Wootton]

I have a file which is 275,000 lines long and I only want the last 25,000 so I can put then in Excel for analysis. How can I get them using the tail command ?

Hi Simon,

Use

tail -n 25000
Hope this helps,

Thanks

$ tail -n 25000

Do "man tail" for details of available option.

Hi,

Try

tail -25000 file_name > new_file_name

Hope this helps.

tail -n 25000 infile > outfile

You can try

tail -25000 inputfile

You might prefer to use split instead:

split -250000 inputfile

and import the file "xab" into Excel.

Hi SImon:

'tail' will not handle very large files. You can use 'sed' to mimic 'head' and 'tail'. For example:

# sed -e '1,5d' myfile #...removes lines 1-5

# sed -e '1,5!d' myfile # ...keeps only lines 1-5

Regards!
