У меня есть файл, мое имя файла lookup.txt. Иногда содержимое этого файла составляет 100 строк, поэтому во время печати все прокручивается. Вот почему мне нравится печатать его на экране в 2 или более столбцах.
my bash не поддерживает такие команды, как pr или columns. Нужно быть в старомодной оболочке.
Содержимое поиска файл:
1-Top Scores
2-Last Scores
3-Username
4-Birthday
5-Last Meal today
6-Coronavirus in Italy
7-Lets Stay Home
8-Winner
9-Germany and Belgium
10-Alfa
11-Bravo
12-Charlie and delta
Для печати в столбцах я использую эту команду, найденную здесь в stackoverflow:
cat lookup.txt | xargs printf '%-24s\n' | sed '$p;N;s/\n//;$p;N;s/\n//'
, и это печать в столбцах:
1-Top Scores 2-Last
Scores 3-Username 4-Birthday
5-Last Meal today
6-Coronavirus in Italy
7-Lets Stay Home
8-Winner 9-Germany and
Belgium 10-Alfa 11-Bravo
12-Charlie and delta
Мне нужно, чтобы sed не разделял слова на разные столбцы, а только на строку.
1-Top Scores 6-Coronavirus in Italy 11-Bravo
2-Last Scores 7-Lets Stay Home 12-Charlie and delta
3-Username 8-Winner
4-Birthday 9-Germany and Belgium
5-Last Meal today 10-Alfa
если 3 столбца имеют ширину, то x символов затем печатаются в 2 столбцах (последний необязательно)
спасибо заранее
