An example of the recently used shell and awk is provided.

Mainly shell several common operations: 1 shell and awk combined with 2 shell string operations 3 shell file operations and awk combined 4 file MD5 verification 5 results output 6 passing parameters, etc.

 

 

The following content cannot be completely correct, but is not a copy of the original text.

 

$ Sh test. Sh tablename 20090310

 

Use the preceding statements to call shell. tablename and 20090310 are two parameters.

 

It is also assumed that there is a log file *. log. Generally, the use of awk also analyzes many logs.

 

Assume that log. log has the following text: systemname '2017-02-28 10:00:00 '123 '...

 

SH Content:

 

# Note

Servername = 192.168.10.1

Tablename = $1

Filedate = $2

Interfacefilename = log. Log

 

CD./log

 

 

Logfilename = log _ $ tablename. Log

Echo $ logfilename

 

Interfacename = int

Interfacename =$ {interfacename }_$ {tablename: 1}

Interfacename =$ {interfacename }_$ {filedate} _. Log

Echo interfacename

 

Filesize = $ (LS-L $ logfilename | awk '{print $5 }')

 

Filedate = $ (cat $ logfilename | gawk-F/''{print $2 }')

 

Filemd5 =$ (md5sum $ logfilename | awk '{print $1 }')

 

# Output file

 

Echo "$ servername | interfacename | filesize |..." >$ {interfacefilename}
