No output for ssh host "awk '{print $0}' /path/to/log.txt" -


i'm trying pull data out of logs on remote machines using awk, , have noticed if ssh machine , run

awk '{print $0}' /path/to/log.txt

i expected output (containing log messages, stack traces, etc.), if run

ssh host "awk '{print $0}' /path/to/log.txt"

then output looks following:

0 1 0 0 1 1 1 1 1 1

any ideas why may happening?

escape dollar sign.

ssh host "awk '{print \$0}' /path/to/log.txt"

because single quotes don't protect $0 on local side, gets substituted befor it's sent remote side.

you try:

ssh host 'awk "{print \$0}" /path/to/log.txt'

that protects $0 on remote side, takes more changes command.
