AWK是否可以读取时间字段并将其用于排序? [英] AWK is it possible to read a time field and use it for sorting?
问题描述
我有两个文件,我需要根据时间列对行进行排序和合并:
I have two files and I need to sort and merge the rows based on the time column:
文件A:
"2014-02-26 16:03:04" "Login Success|isNoSession=false" id=csr,ou=user,dc=openam,dc=forgerock,dc=org 7efb2f0e035a0e3d01 10.17.174.30 INFO dc=openam,dc=forgerock,dc=org "cn=dsameuser,ou=DSAME Users,dc=openam,dc=forgerock,dc=org" AUTHENTICATION-100 DataStore "Not Available" 10.17.174.30
文件B:
"2014-02-26 16:02:27" "Login Failed" dennis "Not Available" 10.17.174.30 INFO dc=openam,dc=forgerock,dc=org "cn=dsameuser,ou=DSAME Users,dc=openam,dc=forgerock,dc=org" AUTHENTICATION-200 DataStore "Not Available" 10.17.174.30
"2014-02-26 16:02:37" "Login Failed" purva "Not Available" 10.17.174.30 INFO dc=openam,dc=forgerock,dc=org "cn=dsameuser,ou=DSAME Users,dc=openam,dc=forgerock,dc=org" AUTHENTICATION-200 DataStore "Not Available" 10.17.174.30
我需要合并文件(非常标准的文件),但是我必须根据第1列中的时间将行插入最终文件中.我还需要为每行修改其他几项,但是我敢肯定,我可以确定那出来.我对基于时间列的排序感到困惑.
I need to merge the files (pretty standard) but I have to insert the rows into final file based on time found in column 1. I have several other items to modify for each line but I'm pretty sure I can figure that out. The sorting based on time column has me stumped.
因此,在这种情况下,我将有一个文件,文件A的行结尾.
So in this case I would have a file with the line from File A at the end.
其他详细信息.
只是为了刷新自己的语言,我正在分析第一个文件.这是我到目前为止的内容:
Just to refresh myself on gawk I was working on parsing the first file. Here is what I have so far:
#!/bin/awk -f
BEGIN {
FS="\t";
}
{
# if we have more than 12 fields for the current row, proceed
if ( NF > 12 )
{
# start looking for the user name
n = split( $3, var1, ",");
if (n > 4)
{
n2 = split (var1[1], var2, "=");
if (n2 >= 2)
{
# Ignore any line where we do not have "id=xxxxx,..."
if (var2[1] == "id")
{
print $1, "N/A", "N/A", $12, $5, $5, var2[2]
}
}
}
}
}
END {
print "Total Number of records=" NR
}
由于要同时处理两个文件,我可能需要将其移到函数中以使其变得更容易.
I probably need to move that into a function to make it easier since I'm going to be processing two files at the same time.
推荐答案
基于linux
和bash
标记,您可以将两个文件串联起来,按第一个字段对它们进行排序,然后将awk
命令应用于结果:
Based in the linux
and bash
tags, you can concatenate both files, sort them by first field and then apply your awk
command to the result:
cat fileA fileB | sort -t$'\t' -s -k1,1 | awk -f script.awk
