Regex 组合多个正则表达式
我必须对几个字符串执行多个操作来清理它们。我已经能够这样做了,但在bash的多个操作中Regex 组合多个正则表达式,regex,bash,sed,Regex,Bash,Sed,我必须对几个字符串执行多个操作来清理它们。我已经能够这样做了,但在bash的多个操作中 # Getting the Content between START and END var1=$(sed '/START/,/END/!d;//d' <<< "$content") # Getting the 4th Line var2=$(sed '4q;d' <<< "$content") # Stripping all the ne

您可以为此使用awk:
awk 'NR==4{sub(/^[[:blank:]]+/, ""); print}' file
第二个awk:
awk '{sub(/^[[:blank:]]+/, "")}
/^START/{p=1; next}
/^END/{sub(/\[[^]]*\]/, "", s); gsub(/"/, "\\\\&", s); print s; p=0; next}
p{s = s $0}' file
谢谢,但是我想在两个不同的变量中存储输出,虽然我可以在另一个sed中流式传输输出,但是如果可以的话,从这里?另外,我也想转义
“
,忘了在示例中添加它。
awk '{sub(/^[[:blank:]]+/, "")}
/^START/{p=1; next}
/^END/{sub(/\[[^]]*\]/, "", s); gsub(/"/, "\\\\&", s); print s; p=0; next}
p{s = s $0}' file
