- 在cli中對字符串進行md5加密
#!/bin/bash
echo -n $1 | md5sum | awk '{print $1}'
- 在bash中進行urlencode，推薦
function encodeurl()
{
encoded_str=`echo "$*" | awk 'BEGIN {
split ("1 2 3 4 5 6 7 8 9 A B C D E F", hextab, " ")
hextab [0] = 0
for (i=1; i<=255; ++i) {
ord [ sprintf ("%c", i) "" ] = i + 0
}
}
{
encoded = ""
for (i=1; i<=length($0); ++i) {
c = substr ($0, i, 1)
if ( c ~ /[a-zA-Z0-9.-]/ ) {
encoded = encoded c # safe character
} else if ( c == " " ) {
encoded = encoded "+" # special handling
} else {
# unsafe character, encode it as a two-digit hex-number
lo = ord [c] % 16
hi = int (ord [c] / 16);
encoded = encoded "%" hextab [hi] hextab [lo]
}
}
print encoded
}' 2>/dev/null`
}
encodeurl $pa
p=$encoded_str
以下兩種可能有時候會出現BUG 不推薦
- 在cli中進行urlencode編碼
echo '加密' | tr -d '\n' | xxd -plain | sed 's/\(..\)/%\1/g'
- 解碼
printf $(echo -n "%e6%89%8b%e6%9c%ba" | sed 's/\\/\\\\/g;s/\(%\)\([0-9a-fA-F][0-9a-fA-F]\)/\\x\2/g')
