Title: SHELL programming, implementation:
/ TMP path has 800 files, the file name is: filename_yyyyymmdd_ serial number (from 001 to
999) .dat, for example: filename_20040108_089.dat
Now I want to rename these files, the format of the new file name is: FileName_Today (current date) _ serial number
(From 500, start from 001 after the 999) .dat,
For example: change filename_20040108_089.dat to filename_20041222_589.dat, pay attention to new text
The order of the serial number of the name needs to be consistent with the original, that is, the ordering process is made.
program:
#! / usr / bin / bash
Dest_file_part2 = "_` Date ' % Y% M% D'`_"
EXT_NAME = ". DAT"
SRC_FILE_LIST = `FIND / TMP -NAME" * _ * _ * $ ext_name "-print`
For each in $ src_file_list; do
DEST_FILE_PART1 = `Echo $ Each | awk -f" _ "'{print $ 1}'`
Old_num = `Echo $ Each | awk -f" _ "'{print $ 3}' | awk -f". '{Print $ 1}' `
DEST_FILE_PART3 = `EXPR $ OLD_NUM 500`
[$ Dest_file_part3 -gt 999] && dest_file_part3 = `expr $ old_num - 499`
&& dest_file_part3 = `Printf% 03D $ dest_file_part3`
DEST_FILE = $ dest_file_part1 $ dest_file_part2 $ dest_file_part3 $ ext_name
Echo "MV $ Each To $ Dest_file"
MV $ Each $ DEST_FILE
DONE
