If each part have the same lines number  for example 22  here my solution  split --numeric-suffixes 2 --additional-suffix  txt -l 22 file txt file and you obtain file2 txt with the first 22 lines  file3 txt the 22 next line     Thank  hamruta-takawale   dror-s and  stackoverflowuser2010

Using bash   readarray -t LINES  lt  file txt COUNT    LINES     for I in     LINES       do     INDEX      I   12 - 1    COUNT   1        echo    LINES I     gt  gt   file  INDEX  txt  done   Using awk   awk        a NR     0   END       for  i   1  i in a    i            x    i   12 - 1    NR   1         sub              x          print a i   gt   file  x   txt           file txt   Unlike split this one makes sure that number of lines are most even

I agree with  CS Pei  however this didn t work for me   split -b 1M -d  file txt file     as the   after -b threw it off  Instead  I simply deleted it and left no space between it and the variable  and used lowercase  m    split -b1m -d  file txt file  And to append   txt   we use what  schoon said    split -b 1m -d  file txt file --additional-suffix  txt  I had a 188 5MB txt file and I used this command  but with -b5m for 5 2MB files   and it returned 35 split files all of which were txt files and 5 2MB except the last which was 5 0MB    Now  since I wanted my lines to stay whole  I wanted to split the main file every 1 million lines  but the split command didn t allow me to even do -100000 let alone  -1000000  so large numbers of lines to split will not work

John s answer won t produce  txt files as the OP wants  Use   split -b 1M -d  file txt file --additional-suffix  txt

You can use the linux bash core utility split          split -b 1M -d  file txt file    Note that M or MB both are OK but size is different  MB is 1000   1000  M is 1024 2  If you want to separate by lines you can use -l parameter    UPDATE  a   wc -l yourfile     lines  echo     a 12     bc -l    split -l  lines -d  file txt file   Another solution as suggested by Kirill   you can do something like the following  split -n l 12 file txt   Note that is l not one  split -n has a few options  like N  k N  l k N  r N  r k N

On my Linux system  Red Hat Enterprise 6 9   the split command does not have the command-line options for either -n or --additional-suffix   Instead  I ve used this   split -d -l NUM LINES really big file txt split files txt    where -d is to add a numeric suffix to the end of the split files txt  and -l specifies the number of lines per file   For example  suppose I have a really big file like this     ls -laF total 1391952 drwxr-xr-x 2 user name group         40 Sep 14 15 43    drwxr-xr-x 3 user name group       4096 Sep 14 15 39     -rw-r--r-- 1 user name group 1425352817 Sep 14 14 01 really big file txt   This file has 100 000 lines  and I want to split it into files with at most 30 000 lines  This command will run the split and append an integer at the end of the output file pattern split files txt      split -d -l 30000 really big file txt split files txt    The resulting files are split correctly with at most 30 000 lines per file     ls -laF total 2783904 drwxr-xr-x 2 user name group        156 Sep 14 15 43    drwxr-xr-x 3 user name group       4096 Sep 14 15 39     -rw-r--r-- 1 user name group 1425352817 Sep 14 14 01 really big file txt -rw-r--r-- 1 user name group  428604626 Sep 14 15 43 split files txt 00 -rw-r--r-- 1 user name group  427152423 Sep 14 15 43 split files txt 01 -rw-r--r-- 1 user name group  427141443 Sep 14 15 43 split files txt 02 -rw-r--r-- 1 user name group  142454325 Sep 14 15 43 split files txt 03     wc -l   txt      100000 really big file txt      30000 split files txt 00      30000 split files txt 01      30000 split files txt 02      10000 split files txt 03     200000 total
