laizhebujum

原始文本
/res/other/jar/mhdb/hyrz/hyrz496.jar
需要提取出
/res/other/jar/mhdb/hyrz/

122285969

1. $ echo $(dirname /res/other/jar/mhdb/hyrz/hyrz496.jar)/
   
2. /res/other/jar/mhdb/hyrz/

    使用awk呢？

biliwei

echo "/res/other/jar/mhdb/hyrz/hyrz496.jar"|awk -F \/ '{print $2,$3,$3,$4,$5,$6}'

ywlscpl

awk -F/ '{sub($NF"$","")}1'

biliwei

echo "/res/other/jar/mhdb/hyrz/hyrz496.jar"|awk -F \/ '{print "/"$2"/","/"$3"/","/"$3"/","/"$4"/","/"$5"/","/"$6"/"}'

$ echo "/res/other/jar/mhdb/hyrz/hyrz496.jar" | sed 's/\(.*\/\).*/\1/'

不拘泥于awk就办法多了
echo "/res/other/jar/mhdb/hyrz/hyrz496.jar"|sed 's/[^/]*$//g'
/res/other/jar/mhdb/hyrz/

原来sed 's/[^/]*$//g'中匹配的/不用转义

$ dirname /res/other/jar/mhdb/hyrz/hyrz496.jar
/res/other/jar/mhdb/hyrz

$ file="/res/other/jar/mhdb/hyrz/hyrz496.jar"
$ echo ${file%/*}
/res/other/jar/mhdb/hyrz
