Ho开发者_Python百科w to print just the last line of a file?
$ cat file | awk 'END{print}'

Use the right tool for the job. Since you want to get the last line of a file, tail is the appropriate tool for the job, especially if you have a large file. Tail's file processing algorithm is more efficient in this case.
tail -n 1 file
If you really want to use awk,
awk 'END{print}' file
EDIT : tail -1 file
deprecated
Is it a must to use awk
for this? Why not just use tail -n 1 myFile
?
Find out the last line of a file:
Using sed (stream editor):
sed -n '$p' fileName
Using tail:
tail -1 fileName
using awk:
awk 'END { print }' fileName
You can achieve this using sed
as well. However, I personally recommend using tail
or awk
.
Anyway, if you wish to do by sed
, here are two ways:
Method 1:
sed '$!d' filename
Method2:
sed -n '$p' filename
Here, filename is the name of the file that has data to be analysed.
