[Solved] Bash command to update a variable

Gleno0h

@temp this is already build in? WHEN its 22:00 THEN …?

And what do you mean by wrong port number? You have it fixed because you used the wrong port?

Also, what time do you want to send?
System time or just “17:00” ?

"valueOrExpression": "17:00"

temp

Yes, i fixed it with the correct port number.

The variable has then the value 2.10.2017-17:00:00 and the rule shoud check if it is 2.10.2017-17:00:00 and switch on the wall plug.

Gleno0h

@temp idk what you exactly want but ill give you a hint.

Lets define the time first:

systemtime=$(date '+%X')

You can now manipulate how you want to output the time. Experiment with it.

Then, to use it with curl:

curl --silent -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "'$systemtime'"}' --user "test:test" http://IPADDRESS/api/variables/your_variable > /dev/null

So, paste this in your bash:

systemtime=$(date '+%X')

curl --silent -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "'$systemtime'"}' --user "test:test" http://IPADDRESS/api/variables/your_variable > /dev/null

This will write 11:20:10 to your variable.

Want only the current day?
Use date '+%A'
want day and time?
Use ```date ‘+%A %X’``

Or simply use
systemtime="2.10.2017-17:00:00" if you want to use a fixed time

@temp i dont know. Post your bash script?

I also see you have date in ’ ’ tags, thats wrong. I also see $ t. Why is there a space? Should be $t.

Post your bash pls

Hello,

  t=`date -d@$timestamp +%d-%m-%Y\ %H:%M`
 curl -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "'$t'"}' --user "a:a" http://smarthome:5001/api/variables/variable_string_today

mwittig

@temp Looks like the command spans multiple lines including line breaks. Note, line breaks are not supported and need to be escaped with an \ at the end of the line, e.g.

curl -X PATCH --header "Content- \     
 Type:application/json" --data '{"type": "value",\
  "valueOrExpression": "'$t'"}' --user "a:a"  \
      http://smarthome:5001/api/variables/variable_string_today

Gleno0h

@temp what @mwittig said and following line doesnt make sense to me…

t=`date -d@$timestamp +%d-%m-%Y\ %H:%M`

t=date -d ‘+%d-%m-%Y\ %H:%M’ makes more sense to me, except for -d. Thats invalid… Why do you have @$timestamp?

Also why the \ ?

Please let me know what you want and ill post a bash code you can copy and use.

everything is fine if I use

instead of

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y\ %H:%M`

If I am using this line for defining the Start time

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y\ %H:%M`

When I use this line

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y/%H:%M`

Everything is good

But i like to see in the pimatic GUI the format

16-05-2017 17:30

And not

16-05-2017/17:30

Gleno0h

@temp well, you define it yourself in your date command…

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y/%H:%M`

But you want:

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y %H:%M`

As you can see, i only removed the /…

NSA@raspberrypi:~# date '+%d-%m-%Y/%H:%M'
16-05-2017/23:46
NSA@raspberrypi:~# date '+%d-%m-%Y %H:%M'
16-05-2017 23:46

@Gleno0h said in Bash command to update a variable:

@temp what @mwittig said and following line doesnt make sense to me…

My comment was referring to the following error and the command snippets @temp sent in post 11, but I have been misled by the strange formatting he used in his post.

curl: (3) [globbing] unmatched close brace/bracket in column 7
SyntaxError: Unexpected end of input

@temp Actually, I think the problem is bad quotation. The following modified command sequence based on post 11 works for me. See also 2nd post at https://superuser.com/questions/835587/how-to-include-environment-variable-in-bash-line-curl for details.

pi@raspi3:~ $ stop_timestamp=1494910730
# Space in the date format string below must be escaped

{"variable":{"name":"variable_string_today","readonly":false,"type":"value","value":"16-05-2017 06:58","unit":""},"success":true}

EDIT: @temp In your example the inner double quotes for the variable are missing which expands to the following as the shell with quote the space character for you.... "valueOrExpression": "16-05-2017' '06:58". That’s causing the syntax error. You can easily trace that yourself by setting set -x in your shell.

@Gleno0h said in Bash command to update a variable:

wake_start_time=date -d@$wake_start_timestamp +%d-%m-%Y %H:%M

This wont’t work. The space must be escaped with a backslash \. Otherwise you will get the syntax error in the curl command. It won’t work from the command line, either.

pi@raspi3:~ $ wake_start_timestamp=1494910730                                                                                                                                          
pi@raspi3:~ $ date -d@$wake_start_timestamp +%d-%m-%Y %H:%M
date: zusätzlicher Operand „%H:%M“
„date --help“ liefert weitere Informationen.
pi@raspi3:~ $ date -d@$wake_start_timestamp +%d-%m-%Y\ %H:%M
16-05-2017 06:58

EDIT: Alternatively, you can do the following which is more or less what you suggested

pi@raspi3:~ $ date -d@$wake_start_timestamp '+%d-%m-%Y %H:%M'
16-05-2017 06:58

As you can see, i only removed the /…

No, you also added single quotes around the format string.
