awk 排版格式沒對齊, 大概這樣

|  01-26 午 -----     |    |     |
|  H8     | 70k/12/3s   | wide pulldown   |
|  AB7    | 55/12/3s    | torso rotation  |
|  PC2b   | 55/15/3s    | rear delt/pec fly  |
|  PC2    | 90/15/3s    | rear delt/pec fly  |
|  lh1    | 50k/15/3s   | glute  |

原始格式

Subject: 01-26 午 -----::
Subject: H8:70k/12/3s:wide pulldown
Subject: AB7:55/12/3s:torso rotation
Subject: PC2b:55/15/3s:rear delt/pec fly
Subject: PC2:90/15/3s:rear delt/pec fly
Subject: lh1:50k/15/3s:glute

用 perl 程式, 排版改成固定欄寬比較好看..

續 iPhone note 建身記錄轉成 dokuwiki 表格
將四個 sed 指令 (移除開頭及排版 dokuwiki 格式) 改成 awk

原 sed 指令

sed -e "s/Subject: //g" 2016mmdd_note_org > 2016mmdd_note_w1

sed -e "s/:/|/g" 2016mmdd_note_w2 > 2016mmdd_note_w3
sed -e "s/^/|/g" 2016mmdd_note_w3 > 2016mmdd_note_w4
sed -e "s/$/|/g" 2016mmdd_note_w4 > 2016mmdd_note_w5
