Top Forums Shell Programming and Scripting Find -name "*.txt" in Korn Shell Script Post 24857 by jwperry on Thursday 18th of July 2002 02:18:05 PM

I was thinking I could get away with minimal detail on my first post, but, I was wrong - sorry about that. The script actually accepts parameters that will be used in the find command. I echo the find command to screen, and it 'looks ok" - see snippets below:

#!/bin/ksh
PURGEPATH=$1
DAYSOLD=\'$2\'
FILESPEC=\'$3\'
LOGINDICATOR=$4

###DAYSOLD=$2
###FILESPEC=\\$3 tried this
###FILESPEC=\"$3\" and this


...(The script switches to PURGEPATH)....

The find looks like this:

find . \( ! -name . -prune \) -type f -name $FILESPEC -mtime $DAYSOLD | xargs ls -ldrt >> $LOGFILE


I echo the 'variable populated' find command to the screen (and logfile), and it looks like:

find . \( ! -name . -prune \) -type f -name '*.txt' -mtime '+100' | xargs ls -ldrt


Finally, I put the 'hard-coded' find in the script, with -name '*.txt' (i.e. exactly the second find, above), and it worked! So, even though I echo the 'variable-populated' version to screen, and, it looks just like the 'hard-coded' version, the variable version ($FILESPEC, $DAYSOLD) does not work!


I hope I made that clear. My login shell is ksh. The script is ksh.
What is it about the use of the variables am I missing?


Thanks again!

NAME
sh - overview of various system shells SYNOPSIS
POSIX Shell option] ... string] [arg ...] option] ... string] [arg ...] Korn Shell option] ... string] [arg ...] option] ... string] [arg ...] C Shell [command_file] [argument_list ...] Key Shell DESCRIPTION
Remarks The POSIX .2 standard requires that, on a POSIX-compliant system, executing the command activates the POSIX shell (located in file on HP-UX systems), and executing the command produces an on-line manual entry that displays the syntax of the POSIX shell command-line. However, the command has historically been associated with the conventional Bourne shell, which could confuse some users. To meet stan- dards requirements and also clarify the relationships of the various shells and where they reside on the system, this entry provides com- mand-line syntax and a brief description of each shell, and lists the names of the manual entries where each shell is described in greater detail. The Bourne shell is removed from the system starting with HP-UX 11i Version 1.5. Please use the POSIX shell as an alternative. Shell Descriptions The HP-UX operating system supports the following shells: POSIX-conforming command programming language and command interpreter residing in file Can execute commands read from a terminal or a file. This shell conforms to current POSIX standards in effect at the time the HP-UX system release was introduced, and is similar to the Korn shell in many respects. Similar in many respects to the Korn shell, the POSIX shell contains a history mechanism, supports job control, and provides various other useful features. Korn-shell command programming language and commands interpreter residing in file Can execute commands read from a terminal or a file. This shell, like the POSIX shell, contains a his- tory mechanism, supports job control, and provides various other useful features. A command language interpreter that incorporates a command history buffer, C-language-like syntax, and job control facilities. Restricted version of the POSIX shell command interpreter. Sets up a login name and execution environment whose capabilities are more controlled (restricted) than normal user shells. restricted version of the Korn-shell command interpreter Sets up a login name and execution environment whose capabilities are more controlled (restricted) than normal user shells. An extension of the standard Korn Shell that uses hierarchical softkey menus and context-sensitive help. +--------------+--------------------+ | To obtain: | Use the command: | +--------------+--------------------+ | POSIX Shell | /usr/bin/sh ... | | Korn Shell | /usr/bin/ksh ... | | C Shell | /usr/bin/csh ... | | Key Shell | /usr/bin/keysh | +--------------+--------------------+ These shells can also be the default invocation, depending on the entry in the file. See also chsh(1). WARNINGS
Many manual entries contain descriptions of shell behavior or describe program or application behavior similar to ``the shell'' with a ref- erence to ``see sh(1)''. SEE ALSO
