Hi experts,

i have some problem with inserting text to a file, i have a file named test.log output like this :

11111 22222 33333 44444 55555

i want to insert date into the file test.log, expected output is :

20070501 11111 22222 33333 44444 55555

any idea?

please help

Thank you

perl -i -ne ' print "20070501 $_" ' file

alternatively you could use

dt=$(date +%Y%m%d)
sed '1,$s/^/'$dt'/g file

should be a typo..
it should be
sed '1,$s/^/'$dt' /g' file

(added a space after '$dt' as per the OP's output )

or

just this would do,
sed '/^/'$dt' /g' file :slight_smile:
