4 Sockets in /var/run/screen/S-kreezxil.
Eu criei um script que gera um menu para os consoles Detached.
#!/bin/bash
IDX=0
declare -a pids
declare -a names
for f in $(screen -ls); do
if [[ $f = *"MASTER"* ]]; then
IFS="." read -r -a data <<< "$f"
pids[IDX]="${data[0]}"
IFS="_" read -r -a name <<< "${data[1]}"
names[IDX]="${name[0]}"
((++IDX))
fi
done
size=${#pids[@]}
while true; do
clear
printf '\nSCREEN\tPID\tNAME\n'
for (( i=0; i<${size}; i++ )); do
printf '%s\t%s\t%s\n' ${i} ${pids[i]} ${names[i]}
done
printf '\nWhich screen # would you like to resume?\nEnter to q to quit or exit\n'
read n
if [ $n == 'q' ]; then
exit
fi
if [ $n -lt 0 || $n -gt $size ]; then
read -p "Invalid Option: Press [Enter] to try again" readEnterkey
continue
fi
screen -r ${pids[$n]}
done
Pode selecionar ser usado para tornar o script mais elegante, se sim, como? (esta é uma questão primordial)
Nota: desejo manter a legibilidade do script. Sugestões: congratulou-se com.
