I have a file with million records and each line ends with SYSTEM;\\N
.
I want to delete all occurrences of ;\\N
from file. How can I approach this?
You can use the sed command to replace all the occurrences of the ';\\N' from the file and replace it with ''.
sed -i 's/original/new/g' file.txt
Explanation:
sed = Stream EDitor
-i = in-place (ie save back to the original file)
The command string: s = the substitute command
original = a regular expression describing the word to replace (or just the word itself)
new = the text to replace it with
g = global (ie replace all and not just the first occurrence)
file.txt = the file name
这终于奏效了sed -i '' 's/;\\\\N//g' test112.csv
