1) Every shell file gegins with #!/[path to shell]/[name of shell]! to use bash, for example you would begin your shell script with
to use tcsh you could use
2) When you declare variables just type the variable name followed by the = sign. For example to create a variable named NAME and set it to "ME" enter
3) When using a variable in an expression (like an if, and so forth) precede the variable name by $. For example, to ser a variable caled VAR2 to NAME enter:
4) You can use commands in shell scripts as you do the shell. The advantage of shell scripts is that you can use macros. For example to list all files and all directories in the current directory that begin with NAME enter
ls $NAME*
The following file gets all of the files returned by ls and stroes them in foo. after that, it takes the last file listed by ls and stores it in final value. Then it prints the value of finalvalue.
I would list more, but I ran out of time. Hope this helps.

When getting a listing of files using "ls -l", my output shows the permissions, #oflinks???, owner, group, size, month-day-time, and file.
In the example below, how would I know what year the file was last modified?

platform::shell
platform::shell(n) Tcl Bundled Packages platform::shell(n)
__________________________________________________________________________________________________________________________________________________NAME
platform::shell - System identification support code and utilities
SYNOPSIS
package require platform::shell ?1.1.4?
platform::shell::generic shell
platform::shell::identify shell
platform::shell::platform shell
_________________________________________________________________DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.
This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
requirement is that the other shell (identified by its path), is actually executable on the current machine.
While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell
this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.
For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed
packages, versus the architecture of the shell running the repository software.
COMMANDS
platform::shell::identify shell
This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.
platform::shell::generic shell
This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.
platform::shell::platform shell
This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
KEYWORDS
operating system, cpu architecture, platform, architecture
