Exec command with single quotes about sake

[enriquetoledano]

Hi!

This method isn't working for me:

sake exec -s server -o table $'uname -r | awk -v FS=\'-\' \'{print $1}\''

TASKS ***************************************************************************************************

 host       | task-0
------------+---------------------------------------------------------------
 x.x.x.x | awk: cmd. line:1: {print
            | awk: cmd. line:1:       ^ unexpected newline or end of string
            |
            | Process exited with status 1

RECAP ***************************************************************************************************

 x.x.x.x      ok=0  unreachable=0  ignored=0  failed=1  skipped=0

The only way I could make it work was:

sake exec -s server $'uname -r | awk -v FS=\'-\' "{print $ 1}"'

That is, using doble quote for print and with a space between $ and number.

When defined as a task, it runs correctly when using:

  print-kernel:
    name: Kernel
    desc: Print kernel version
    spec: info
    target: all
    cmd: uname -r | awk -v FS='-' "{print $ 1}"

Thank you very much for your help!

Double quotes work for me.

~ $ sake exec -s log "uname -r|awk -v FS='-' '{print $1}'"

Hi:

Thanks for your quick response.
For me, it keep failing:

$:~# sake exec -s server "uname -r|awk -v FS='-' '{print $1}'"

TASK [task-0] ******************************************************************************************************************************

x.x.x.x | awk: cmd. line:1: {print
x.x.x.x | awk: cmd. line:1:       ^ unexpected newline or end of string
x.x.x.x | Process exited with status 1

RECAP **************************************************************************************************************************************

 x.x.x.x      ok=0  unreachable=0  ignored=0  failed=1  skipped=0

I'm using Ubuntu 20.04, go 1.9 and latest version of sake.

For you, I think it doesn't work either. The output of your command must be 5.15.76, not 5.15.76-v8+. The awk part isn't working.

Best regards

You're correct, this seems to work correct:

sake exec -s log -o table $'uname -r | awk -v FS=\'-\' \'{print $1}\''

Use $'my \'string\'' to escape characters
