how to use/get a section from selection

[daniejstriata]

I have a list of servers with hostname, IP, location and description separated with = (but could be anything)
server1 = us-east1 = web1 http://example.com
server2 = us-east2 = web2 http://example2.com
server3 = us-west1 = sql

How can I make a selection with fzf but have it only use the hostname section to call ssh? All the solutions I've found so far would cut off the other fields and therefore not get displayed.

ssh server3

separated with = (but could be anything)

• try it with the delimiter flag and FIELD INDEX EXPRESSION
  • see man fzf

Placeholder	Description
{}	current line
{2}	current line with positional field 2
{2..}	current line from the 2nd field to the last field

Placeholder expression flags	Description
+	space-separated list of the selected lines
f	temporary file
s	preserve the whitespace

cat servers.txt |
  fzf --delimiter '=' --preview 'echo {1};echo {2};echo {3}' --preview-window nohidden

---

• within fzf you can then define a hotkey to perform an action, for example execute or become
  • fzf's man page and the the CHANGELOG.md will help

cat servers.txt |
  fzf --delimiter '=' --bind 'enter:become:echo I have selected: {1}'

Thank you! This works for me.
