Как исследовать или исправить случайное зависание жесткого диска ввода-вывода и системы в Linux?

Команда:

c=`awk '{print NR}' file2| sort -nr | sed -n '1p'`;for ((i=1;i<=$c;i++)); do j=`awk -v i="$i" 'NR==i{$1=$2="";print $0}' file1`; awk -v i="$i" -v j="$j" 'NR == i{$3=$2;$2=j;print $0}' file2; done| sed "s/complete genome.txt/complete genome/g"

выход

c=`awk '{print NR}' file2| sort -nr | sed -n '1p'`;for ((i=1;i<=$c;i++)); do j=`awk -v i="$i" 'NR==i{$1=$2="";print $0}' file1`; awk -v i="$i" -v j="$j" 'NR == i{$3=$2;$2=j;print $0}' file2; done| sed "s/complete genome.txt/complete genome/g"
