Print a file skipping the first X lines in Bash

Question

I have a very long file which I want to print  skipping the first 1 000 000 lines  for example  I looked into the cat man page  but I did not see any option to do this  I am looking for a command to do this or a simple Bash program

If you have GNU tail available on your system, you can do the following:

tail -n +1000001 huge-file.log

It's the + character that does what you want. To quote from the man page:

If the first character of K (the number of bytes or lines) is a `+', print beginning with the Kth item from the start of each file.

Thus, as noted in the comment, putting +1000001 starts printing with the first item after the first 1,000,000 lines.

Use   sed -n  1d p    This command will delete the first line and print the rest

You ll need tail   Some examples      tail great-big-file log  lt  Last 10 lines of great-big-file log  gt    If you really need to SKIP a particular number of  first  lines  use    tail -n   lt N 1 gt   lt filename gt   lt  filename  excluding first N lines   gt    That is  if you want to skip N lines  you start printing line N 1  Example     tail -n  11  tmp myfile  lt   tmp myfile  starting at line 11  or skipping the first 10 lines   gt    If you want to just see the last so many lines  omit the         tail -n  lt N gt   lt filename gt   lt  last N lines of file   gt

Use the sed delete command with a range address  For example   sed 1 100d file txt   Print file txt omitting lines 1-100    Alternatively  if you want to only print a known range  use the print command with the -n flag   sed -n 201 300p file txt   Print lines 201-300 from file txt   This solution should work reliably on all Unix systems  regardless of the presence of GNU utilities

If you want to see the first 10 lines you can use sed as below   sed -n  1 10 p  myFile txt   Or if you want to see lines from 20 to 30 you can use   sed -n  20 30 p  myFile txt

A less verbose version with AWK   awk  NR  gt  1e6  myfile txt   But I would recommend using integer numbers

I needed to do the same and found this thread   I tried  tail -n    but it just printed everything   The more  lines worked nicely on the prompt  but it turned out it behaved totally different when run in headless mode  cronjob    I finally wrote this myself   skip 5 FILE   tmp filetoprint  tail -n    cat    FILE     wc -l  - skip      FILE
