Recently, I made the system a new one, so it became a system in which WIN98 and linux coexist. However, after working for a long time, I found it inconvenient (all file names under WIN98 are in uppercase, in linux, the file names are generally lowercase characters ). When using mcopy, the copied file names are in uppercase, which is inconvenient for linux operations!
So I wrote two shell scripts. I used them to facilitate a lot of operations over the past few days. now I want to share them with my friends in dual systems (I know there are a lot of people using dual systems like me! ;-), Someone should be able to use it. The script is very simple, but it is packaged before it is posted (it looks like a system command, huh, huh ). However, you can only change the file name in the current directory (that is, you can only: % upks2lowks * or % upks2lowks myfile, but not % upks2lowks/mydir/myfile, but there will be errors!
The script content is as follows:
　　
#! /Bin/sh
　　
# This Shell Script can change UPPER-case filename to low-case filename.
　　
Error = 0; count = 0
Number = $ (echo * |/usr/bin/wc-w)
　　
If ["$1" = "-h"-o "$1" = "-- help"]; then
Echo "Usage: upks2lowks [PATH] [FILENAME]..."
Echo "Description: Change \" FILENAME \ "to \" filename \"! "
Echo ""
Echo "-h, -- help display this info and exit"
Echo "-v, -- version display version info and exit"
Echo ""
Echo "Report bugs ."
Echo "PS: I think U can modify it by nothing! It's just a shell script! ;-)"
Exit
Fi
　　
If ["$1" = "-v"-o "$1" = "-- version"]; then
Echo "A tool form my file-utils, no version info! "
Echo "(maybe ver0.0.0 )?! (^ O ^ )"
Echo "Written by Juner. L"
Echo ""
Echo "Copyright (C) Juner"
Echo "This is free software; see the source for copying conditions. There is NO"
Echo "warranty; not even for MERCHANTABILITY or fitness for a participant PURPOSE ."
Exit
Fi
　　
If [-z "$1"]; then
/Usr/bin/printf "\"
Echo "Just put the \" FILENAME \ "follow the command! "
Else
For I in $ *
Do
If [-e "$ I"-a-w "$ I"]; then
File = $ (echo $ I |/usr/bin/tr "[A-Z]" "[a-z]")
If ["$ I" = "$ file"]; then
Echo "The file \" $ I \ "is already lowcased! "
Count = $ (/usr/bin/expr 1 + $ count)
Else
Echo "$ I => $ file"
/Bin/mv-f $ I $ file 2>/dev/null
Fi
Else
Echo "warning: file \" $ I \ "not exist OR you have no \" w \ "right to file! "
Fi
Done
If ["$ number"-eq "$ count"]; then
Echo "all file (s) is lowcased! "
Else
Echo "$ count file (s) already lowcased! "
Fi
Fi
　　
There is another one that is similar to it. it only changed a few small places and changed the lowercase file name to uppercase, as shown below:
　　
#! /Bin/sh
　　
# This Shell Script can change low-case filename to UPPER-CASE filename.
　　
Error = 0; count = 0
Number = $ (echo * |/usr/bin/wc-w)
　　
If ["$1" = "-h"-o "$1" = "-- help"]; then
Echo "Usage: lowks2upks [path] [filename]..."
Echo "Description: Change \" filename \ "to \" FILENAME \"! "
Echo ""
Echo "-h, -- help display this info and exit"
Echo "-v, -- version display version info and exit"
Echo ""
Echo "Report bugs ."
Echo "PS: I think U can modify it by nothing! It's just a shell script! ;-)"
Exit
Fi
　　
If ["$1" = "-v"-o "$1" = "-- version"]; then
Echo "A tool form my file-utils, no version info! "
Echo "(maybe ver0.0.0 )?! (^ O ^ )"
Echo "Written by Juner. L"
Echo ""
Echo "Copyright (C) Juner"
Echo "This is free software; see the source for copying conditions. There is NO"
Echo "warranty; not even for MERCHANTABILITY or fitness for a participant PURPOSE ."
Exit
Fi
　　
If [-z "$1"]; then
/Usr/bin/printf "\"
Echo "Just put the \" filename \ "follow the command! "
Else
For I in $ *
Do
If [-e "$ I"-a-w "$ I"]; then
File = $ (echo $ I |/usr/bin/tr "[a-z]" "[A-Z]")
If ["$ I" = "$ file"]; then
Echo "the file \" $ I \ "IS ALREADY UPPERCASED! "
Count = $ (/usr/bin/expr 1 + $ count)
Else
Echo "$ I => $ file"
/Bin/mv-f $ I $ file 2>/dev/null
Fi
Else
Echo "WARING: FILE \" $ I \ "NOT EXIST or YOU HAVE NO \" w \ "RIGHT TO FILE! "
Fi
Done
If ["$ number"-eq "$ count"]; then
Echo "all file (S) is uppercased! "
Else
Echo "$ count FILE (S) already uppercased! "
Fi
Fi
　　
Continued
　　
After learning about gawk, I have optimized the above two scripts. the changed script can change the file name under any Directory (directory/file with write permission,
That is to say, it can be in any Directory
% Upks2lowks/home/juner/tmp /*
Instead of having
% Cd/home/juner/tmp/
% Upks2lowks *
The modified shell script is as follows:
(If the command path is different from that on your machine, change it to the same path)

# This Shell Script can change UPPER-CASE filename to low-case filename.

# End of the "init the vars "!
　　
　　
# Process the parameter (s )!
