Script in bash that works only some of the time
I ran this script yesterday (in the background)
/usr/bin/nohup myfilelocation/myscriptname.sh &

the script worked perfectly.

i ran it today (also in the background) and just sat there. So i killed it and ran it normally and it worked perfectly.
Anyone suggest why it just sat there and didnt work? but worked when i ran it again right after it worked fine?

partial script below

Code:
#!/bin/bash
TZ=date+24
DATE1=`date '+%d%m%y'`
DATE=`date '+%Y%m%d'`

#this bit waits for the file to appear
mytest1=`ls -lart /pathtofile/ | grep -c filename.$DATE.TXT`
while [ $mytest1 -ne 1 ]
do
mytest1=`ls -lart /pathtofile/ | grep -c filename.$DATE.TXT`
while [ $mytest1 -ne 1 ]
sleep 160
done

#this bit waits for the file to finish generating
while [ $mytest15 -ne 1 ]
do
mytest15=`cat /pathtofile/ | grep -c filename.$DATE.TXT | grep TRL | wc -l`
sleep 180
done

goes on to change file name and move it

yesterday

YESTERDAY(1)						      General Commands Manual						      YESTERDAY(1)

NAME

       yesterday - print file names from the dump

SYNOPSIS

       yesterday [ -c ] [ -date ] files ...

DESCRIPTION

       Yesterday prints the names of the files from the most recent dump.  Since dumps are done early in the morning, yesterday's files are really
       in today's dump.  For example, if today is March 17, 1992,

	      yesterday /adm/users

       prints

	      /n/dump/1992/0317/adm/users

       In fact, the implementation is to select the most recent dump in the current year, so the dump selected may not be from today.

       With option -c, yesterday copies the dump file to the current directory.

       The date option selects other day's dumps, with a format of 2, 4, 6, or 8 digits of the form dd, mmdd, yymmdd, or yyyymmdd.

       Yesterday does not guarantee that the string it prints represents an existing file.

EXAMPLES

       Back up to yesterday's MIPS binary of vc:

	      cd /mips/bin
	      yesterday -c vc

       Temporarily back up to March 1's MIPS C library to see if a program runs correctly when loaded with it:

	      bind `{yesterday -0301 /mips/lib/libc.a} /mips/lib/libc.a
	      rm v.out
	      mk
	      v.out

FILES

       /n/dump

SOURCE

       /rc/bin/yesterday

SEE ALSO

BUGS

       It's hard to use this command without singing.
