Help with Shell Scripts Using sed in multiple files.
Hi, I was hoping that someone could help me. I have a problem that i am trying to work on and it requires me to change text within multiple files using sed. What i have so far is
Code:
!/bin/sh
File1="$3"
File2="$4"
File3="$5"
testNum="$File1"
while test "$testNum" <= "$File3";
do
echo "$File3"
A="$1"
echo $A
B="$2"
C="$3"
echo "$A" | sed -e 's/\([*.[^$]\)/\\\1/g' > temporary
A="`cat 'temporary'`"
rm temporary
echo "$A"
sed "s/$A/$B/g" "$C" > myFile.txt.updated
mv myFile.txt.updated "$C"
cat "$C"
done

gzexe
GZEXE(1) General Commands Manual GZEXE(1)NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe [ name ... ]
DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
penalty in performance). For example if you execute ``gzexe /bin/cat'' it will create the following two files:
-r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat
-r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~
/bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file. You can remove /bin/cat~ once you are sure that
/bin/cat works properly.
This utility is most useful on systems with very small disks.
OPTIONS -d Decompress the given executables instead of compressing them.
SEE ALSO gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the
PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).
BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases,
using chmod or chown.
