刪除不在括號內的所有內容

我想刪除不在括號內的所有內容，包括括號，僅在以“>”開頭的行中。有 sed 替代品嗎？另外，想按字母順序對行進行排序，也就是以“>”開頭的行及其下一行。

輸入範例：

>ID:000:FLKLNFIA_00192 |[Ignicoccus_hospitalis_KIN4-I.gbfspecies]|strain|Ignicoccus_hospitalis_KIN4-I.gbf|LSU ribosomal protei..|447|FLKLNFIA_1(1297538):162644-163090:1 ^^ Archaeagenomesparanahui Ignicoccus_hospitalis_KIN4-I.gbfspecies strain strain.|neighbours:ID:000:FLKLNFIA_00191(1),ID:000:FLKLNFIA_00193(1)|neighbour_genes:LSU ribosomal protei..,SSU ribosomal protei..|

預期輸出：

謝謝

與perl：

perl -ne 'push @l, ">" . join("", /\[(.*?)\]/g) . "\n" . <>;
         END{print for sort @l}' your-file

與sed：

<your-file sed 's/^[^[]*\[/>/
               s/\][^[]*\[\{0,1\}//g
               N;s/\n/\[/' |
 sort |
 tr '[' '\n'

我的（複雜的）建議：

cat file | grep -Po "^[CGTA-]*$|^>.*$" | grep -Po "(?<=\[).*(?=])|^[ACGT-]*$" | awk '{printf (NR%2==0) ? $0 "\n" : ">"$0"::"}' | sort | sed 's/#/\n/'

---

grep 僅包含字元CGTA- 的行和以開頭的行>

grep -Po "^[CGTA-]*$|^>.*$"

---

Grep 僅括號內的內容，不包括它們，以及與模式匹配的行ACGT-

| grep -Po "(?<=\[).*(?=])|^[ACGT-]*$"

---

加入每兩行，添加分隔符#和初始>，然後排序

| awk '{printf (NR%2==0) ? $0 "\n" : ">"$0"#"}' | sort

---

最後用#新行替換分隔符

| sed 's/#/\n/'

---

輸出：

>Archaeoglobus_fulgidus_DSM_4304.gbfspecies
ATGCGCGCGATAGCTAGCTAGCTAGCTTTAGGGGGATTAGCTA----ACTCTGATTCGGA
>Ignicoccus_hospitalis_KIN4-I.gbfspecies
