Bash 使用shell脚本解析日志值
我正在尝试编写一个shell脚本来解析日志中灰色行的值:Bash 使用shell脚本解析日志值,bash,shell,sed,Bash,Shell,Sed,我正在尝试编写一个shell脚本来解析日志中灰色行的值: <WhereIsTheCar - the car with id number 'Sys Generated. VARIABLESTRING 1111' is driving to: Canada> <WhereIsTheCar - the car with id number 'Sys Generated. VARIABLESTRING 2222' is driving to: Mexico> <Wh
<WhereIsTheCar - the car with id number 'Sys Generated. VARIABLESTRING 1111' is driving to: Canada>
<WhereIsTheCar - the car with id number 'Sys Generated. VARIABLESTRING 2222' is driving to: Mexico>
<WhereIsTheCar - no car could be found with the following ID number: 'Sys Generated. VARIABLESTRING 3333'>
诚然,我不太擅长编写shell脚本,但我找到了一种“蛮力”方法来获得我想要的值:
i=0
for line in "${grep[@]}"
do
loc[i]=`sed -e "s/.*\:\(.*\)>/\1/" <<< $line | sed -e "s/^[ \t]*//" -e "s/[ \t]*$//" -e "s/^\([\"']\)\(.*\)\1\$/\2/g"`
echo ${loc[i]};
id[i]=`sed -e "s/^.*\'\(.*\)\'.*$/\1/" <<< $line | sed -e "s/^[ \t]*//" -e "s/[ \t]*$//" -e "s/^\([\"']\)\(.*\)\1\$/\2/g"`
echo ${id[i]};
let i++
done
i=0
对于“${grep[@]}”中的行
做
loc[i]=`sed-e“s/*\:\(.*\)>/\1/“awk将使它更容易:
awk -F"('|driving to: |>)" '{printf "%s\n\t%s\n\n", NF==5?$4:"Not Found",$2;next}' file

,而不是awk
或sed
BASH_REMATCH
An array variable whose members are assigned by the =~ binary
operator to the [[ conditional command. The element with index
0 is the portion of the string matching the entire regular
expression. The element with index n is the portion of the
string matching the nth parenthesized subexpression. This vari‐
able is read-only.
所以这应该对你有用
#!/bin/bash
while read -r line; do
[[ $line =~ "is driving to:"(.*)">" ]] && echo ${BASH_REMATCH[1]} || echo "Not Found"
[[ $line =~ \'(.*)\' ]] && echo -e "\t${BASH_REMATCH[1]}\n"
done < "file"
另一种可能是在BASH中使用BASH\u重新匹配
,而不是awk
或sed
