# SERVERS should be a file with a list of servers, each followed by the ii
# command line for that server (except the -s because we start with the server)
# A -i prefix argument will override the one provided here, useful if you want
# a specific server somehwere other than the given hierarchy, but it should be
# noted that the fifo path will still be relative to $PREFIX/$serv/. There are
# then a list of "fifo command" pairs for each server. If a line ends with a "w"
# we wait a few seconds before executing it (default 5). Each server block
# should be separated by a new line. The commands for a given server are
# performed in serial, and each block runs in parallel. I do not do any error
# checking for you, so don't screw up the format. I never claimed this was
# pretty, just that it works for me :-)
# For example, my $SERVERS file (nick and pass changed of course)
# <start of $SERVERS>
# irc.oftc.net -n mynick
# nickserv/in identify mypass w
# in /j #ii
# in /j #suckless
# in /j #heresy
# nickserv/in /l w
# localhost -n mynick -p 13245
# &bitlbee/in identify mypass
# &bitlbee/in blist w
# <EOF>
# TIP: note the use of 'w' both when identifying to nickserv and leaving
#      nickserv. The first one is to give ii some time to connect, the second
#      should wait until after nickserv replies to your identify, so you don't
#      reopen a window when it does so. the "nickserv/in /l w" is at the end
#      so I don't have to wait for that command before executing the others

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
