perl in tcsh
hi,
I am completely new for tcsh scripting. Trying to write a code, need to implement following function there,
Code:
  perl -pi.bak -e 's/filei/file(i+1)/g' data

I want the "i" to increment and this should change the file name as
Code:
i = 1; file1->file2
i=2; file2->file3
and so on

also please let me know how can I introduce "PAUSE" or sleep in tsch based script.

Thanks,

This will increment the digit following 'file':
Code:
perl -i.bak -pe 's/(file)(\d{1,})/$1 . (1 + $2/ge' data


This should give you a pause until you hit enter:
Code:
set thisvar = $<

Hi
Its not working,Smilie here is the error :
Code:
perl -i.bak -pe 's/(file)(\d{1,})/$1 . (1 + $2/ge' card
syntax error at -e line 1, near "$2 }"
Execution of -e aborted due to compilation errors.

Please let me know if I can set this pause as default to be some minutes.

Thanks

Code:
> perl --help
Usage: perl [switches] [--] [programfile] [arguments]
  -0[octal]       specify record separator (\0, if no argument)
  -a              autosplit mode with -n or -p (splits $_ into @F)
  -C[number/list]enables the listed Unicode features
  -c              check syntax only (runs BEGIN and CHECK blocks)
  -d[:debugger]   run program under debugger
  -D[number/list]set debugging flags (argument is a bit mask or alphabets)
  -e program      one line of program (several -e's allowed, omit programfile)
  -F/pattern/     split() pattern for -a switch (//'s are optional)
  -i[extension]   edit <> files in place (makes backup if extension supplied)
  -Idirectory     specify @INC/#include directory (several -I's allowed)
  -l[octal]       enable line ending processing, specifies line terminator
  -[mM][-]module  execute `use/no module...' before executing program
  -n              assume 'while (<>) { ... }' loop around program
  -p              assume loop like -n but print line also, like sed
  -P              run program through C preprocessor before compilation
  -s              enable rudimentary parsing for switches after programfile
  -S              look for programfile using PATH environment variable
  -t              enable tainting warnings
  -T              enable tainting checks
  -u              dump core after parsing program
  -U              allow unsafe operations
  -v              print version, subversion (includes VERY IMPORTANT perl info)
  -V[:variable]   print configuration summary (or a single Config.pm variable)
  -w              enable many useful warnings (RECOMMENDED)
  -W              enable all warnings
  -x[directory]   strip off text before #!perl line and perhaps cd to directory
  -X              disable all warnings



Code:
sleep s # Where 's' is seconds to sleep
