Shell Programming and Scripting

I want to remove first line from a file containing 10K + records and want to put that into a new file.

Tried sed '1d' filename>newfile
This is writing all the records into new file.

Can somebody help please?

Code:

# line number 1 from oldfile into newfile
head -1 oldfile > newfile
# lines 2 - end from oldfile to newfile
awk 'NR>1' oldfile > newfile

Code:

sed -n 1p urfile > first_line.file

sed -n '2,$'p urfile > rest_lines.file

Code:

 $ sed -i -e '1w firstline' -e '1d'  filename.

After the execution of above command,

i) 'firstline' file will have only the first line from the content of filename.
ii) 'filename' will have all the lines except first line.

Hi
The following three cases along with contents of the files are given:

---Content of OldFile.txt---
Switch to insert mode: press i
Switch to command mode: press Esc

1. sed -n 1p OldFile.txt > NewFile.txt
--OldFile.txt--
Switch to insert mode: press i
Switch to command mode: press Esc
--NewFile.txt--
Switch to insert mode: press i
2. sed '1d' OldFile.txt > NewFile.txt
--OldFile.txt--
Switch to insert mode: press i
Switch to command mode: press Esc
--NewFile.txt--
Switch to command mode: press Esc
3. sed '1d' OldFile.txt
--OldFile.txt--
Switch to insert mode: press i
