tail multiple files and grep the output [closed]

Answer 1

the mistake is that you give the files to the grep command and not the tail.

the tail -f needs to get the files as input. try:

tail -f  /var/links/proc2/id/myprocess*/Daily/myprocess*.log | grep --line-buffered "Search this: "

to get also the file names (however it will not be like grep output it is):

tail /var/links/proc2/id/myprocess*/Daily/myprocess*.log | grep --line-buffered -e'^==> .* <==$' -e'Search this: '
