arch=hello echo -ne $arch | sed 's/^\(.\).*/\1/g'[size=16px]
echo -n "$1" | wc -c | sed 's/ //g' 什么意思
帮忙详细解释一下这句shell语句(path="`echo $0 | sed 's,//*,/,g'`")的意思,
if [ -z $(echo $1 | sed -e 's/[0-9]//g') ]; then
Shell脚本,sed 's/^.*credit=//g'|sed 's/\s.*$//g'
ARCH OF TRIUMPH怎么样
The Arch of Triumph.
an arch enemy
请教命令行:sed "s/,*\(.*\),/\1/g"
正则表达式 echo $1 > 1.tmp sed -e :a -e 's/\(.*[0-9]\)\([0-9]\{3\
为什么死敌叫做 arch-enemy,arch做什么解释?
triumphal arch的音标是什么?
