Operating Systems AIX substringing non field non seperated text Post 302312366 by bakunin on Friday 1st of May 2009 05:51:10 AM

The ksh93 has a substring function you could use, but AIX 4.2 uses a ksh88 as the default shell and it is probably more robust to rely on that.

In this case you could use the variable expansion feature of the ksh to extract the strings:

${var%%???} gives everything except the last 3 characters of variable $var
${var##???} gives everything except the first 3 characters of variable $var
etc.

It is possible to nest these expressions to get a substring-like functionality. Have a look in a ksh book to find out more about variable expansion.

I hope this helps.

#include <tclExtend.h> Tcl_Obj * TclX_NewKeyedListObj (void); int TclX_KeyedListGet (Tcl_Interp *interp, Tcl_Obj *keylPtr, char *key, Tcl_Obj **valuePtrPtr); int TclX_KeyedListSet (Tcl_Interp *interp, Tcl_Obj *keylPtr, char *key, Tcl_Obj *valuePtr); int TclX_KeyedListDelete (Tcl_Interp *interp, Tcl_Obj *keylPtr, char *key); int TclX_KeyedListGetKeys (Tcl_Interp *interp, Tcl_Obj *keylPtr, char *key, Tcl_Obj **listObjPtrPtr); DESCRIPTION
These routines perform operations on keyed lists. See the Extended Tcl man page for a description of keyed lists. TclX_NewKeyedListObj Create and initialize a new keyed list object. Returns: A pointer to the object. TclX_KeyedListGet Retrieve a key value from a keyed list. Parameters: o interp - Error message will be return in result if there is an error. o keylPtr - Keyed list object to get key from. o key - The name of the key to extract. Will recusively process sub-keys seperated by `.'. o valueObjPtrPtr - If the key is found, a pointer to the key object is returned here. NULL is returned if the key is not present. Returns: o TCL_OK - If the key value was returned. o TCL_BREAK - If the key was not found. o TCL_ERROR - If an error occured. TclX_KeyedListSet Set a key value in keyed list object. Parameters: o interp - Error message will be return in result object. o keylPtr - Keyed list object to update. o key - The name of the key to extract. Will recusively process sub-key seperated by `.'. o valueObjPtr - The value to set for the key. Returns: TCL_OK or TCL_ERROR. TclX_KeyedListDelete Delete a key value from keyed list. Parameters: o interp - Error message will be return in result if there is an error. o keylPtr - Keyed list object to update. o key - The name of the key to extract. Will recusively process sub-key seperated by `.'. Returns: o TCL_OK - If the key was deleted. o TCL_BREAK - If the key was not found. o TCL_ERROR - If an error occured. TclX_KeyedListGetKeys Retrieve a list of keyed list keys. Parameters: o interp - Error message will be return in result if there is an error. o keylPtr - Keyed list object to get key from. o key - The name of the key to get the sub keys for. NULL or empty to retrieve all top level keys. o listObjPtrPtr - List object is returned here with key as values. Returns: o TCL_OK - If the zero or more key where returned. o TCL_BREAK - If the key was not found. o TCL_ERROR - If an error occured. Tcl Tcl_GetKeyedListKeys(3tclx)
