Conditional execution of statements
Hi ,

I have a script which has multiple awk and sed commands like below.

Code:
 
First one :- 
find /root/src/  -name "*csv" -size 0 -exec rm {} \;

Second one: -
ls *SRE*.txt > SRT_TRAN.dat
 
rm *asr*.txt
 
Third one :-
 
find /root/src/ -name '*.csv' | while read FILENAME ;
do
awk -F, -v fn="${FILENAME##*/}" '{print fn, $0}' OFS="," "$FILENAME" > "${FILENAME}.txt"
done

What I am trying to do is execute the second command if first command is succesfull , execute the thrid command if second command is sucesfull, some times I will not have any files with *SER* and *asr*, in these cases i don't want the script to fail., it should come out sucessfully with out any error code and the subsequent script should not execute.

Please tell me how to do this.

Regards,
Shruthi

LEARN ABOUT SUSE

info

INFO(1) 							   User Commands							   INFO(1)

NAME

       info - read Info documents

SYNOPSIS

       info [OPTION]... [MENU-ITEM...]

DESCRIPTION

       Read documentation in Info format.

OPTIONS

       -k, --apropos=STRING
	      look up STRING in all indices of all manuals.

       -d, --directory=DIR
	      add DIR to INFOPATH.

       --dribble=FILENAME
	      remember user keystrokes in FILENAME.

       -f, --file=FILENAME
	      specify Info file to visit.

       -h, --help
	      display this help and exit.

       --index-search=STRING
	      go to node pointed by index entry STRING.

       -n, --node=NODENAME
	      specify nodes in first visited Info file.

       -o, --output=FILENAME
	      output selected nodes to FILENAME.

       -R, --raw-escapes
	      output "raw" ANSI escapes (default).

       --no-raw-escapes
	      output escapes as literal text.

       --restore=FILENAME
	      read initial keystrokes from FILENAME.

       -O, --show-options, --usage
	      go to command-line options node.

       --subnodes
	      recursively output menu items.

       --vi-keys
	      use vi-like and less-like key bindings.

       --version
	      display version information and exit.

       -w, --where, --location
	      print physical location of Info file.

       The first non-option argument, if present, is the menu entry to start from; it is searched for in all `dir' files along INFOPATH.  If it is
       not present, info merges all `dir' files and shows the result.  Any remaining arguments are treated as the names of menu items relative	to
       the initial node visited.

       For a summary of key bindings, type h within Info.

EXAMPLES

       info   show top-level dir menu

       info info
	      show the general manual for Info readers

       info info-stnd
	      show the manual specific to this Info program

       info emacs
	      start at emacs node from top-level dir

       info emacs buffers
	      start at buffers node within emacs manual

       info --show-options emacs
	      start at node with emacs' command line options

       info --subnodes -o out.txt emacs
	      dump entire manual to out.txt

       info -f ./foo.info
	      show file ./foo.info, not searching dir
