I need to duplicate the values and put them into the file after each line with value +1. The file I will receive will not be like this every time, so I'll need to store every value to variable.
text.txt
12345
12346
12347
12348
12349
Result I want
12345 12346
12346 12347
12347 12348
12348 12349
How can I do this with Ansible or shell command?
For example, given the file
shell> cat /tmp/text.txt
12345
12346
12347
12348
12349
Read the file and create the block
- command: cat /tmp/text.txt
register: result
- debug:
msg: |-
{% for i in result.stdout_lines %}
{{ i }} {{ i|int + 1 }}
{% endfor %}
gives
msg: |-
12345 12346
12346 12347
12347 12348
12348 12349
12349 12350
Write the block into a file if you want to
- copy:
dest: /tmp/text2.txt
content: |-
{% for i in result.stdout_lines %}
{{ i }} {{ i|int + 1 }}
{% endfor %}
gives
shell> cat /tmp/text2.txt
12345 12346
12346 12347
12347 12348
12348 12349
12349 12350
Example of a complete playbook
- hosts: localhost
tasks:
- command: cat /tmp/text.txt
register: result
- debug:
msg: |-
{% for i in result.stdout_lines %}
{{ i }} {{ i|int + 1 }}
{% endfor %}
- copy:
dest: /tmp/text2.txt
content: |-
{% for i in result.stdout_lines %}
{{ i }} {{ i|int + 1 }}
{% endfor %}
