Shell Script to change a user password using script
Hi Experts,

I had tried to executes this script to change the user password through script:

No lines in buffer
#!/bin/ksh
cat /etc/passwd | grep -v userid >> /tmp/pass.tmp1
cat /etc/passwd | grep userid >> /tmp/pass.tmp2
PASS1=`cat /tmp/pass.tmp2 | cut -d ":" -f2`
PASS2=`q2w3e4r5`
sed 's/$PASS1/$PASS2/g' /tmp/pass.tmp2 > TMPFILE && mv TMPFILE /tmp/pass.tmp2
cat /tmp/pass.tmp2 >> /tmp/pass.tmp1
mv /tmp/pass.tmp1 /etc/passwd



After executing i am getting the following error messages:
mlbept0340-root> sh -x -v testpasswd
#!/bin/ksh
cat /etc/passwd | grep -v userid >> /tmp/pass.tmp1
+ cat /etc/passwd
+ grep -v userid
+ 1>> /tmp/pass.tmp1
cat /etc/passwd | grep userid >> /tmp/pass.tmp2
+ grep userid
+ cat /etc/passwd
+ 1>> /tmp/pass.tmp2
PASS1=`cat /tmp/pass.tmp2 | cut -d ":" -f2`
+ + cat /tmp/pass.tmp2
+ cut -d : -f2
PASS1=*
PASS2=`q2w3e4r5`
+ + q2w3e4r5
testpasswd[5]: q2w3e4r5: not found.
PASS2=
sed 's/$PASS1/$PASS2/g' /tmp/pass.tmp2 > TMPFILE && mv TMPFILE /tmp/pass.tmp2
+ sed s/$PASS1/$PASS2/g /tmp/pass.tmp2
+ 1> TMPFILE
+ mv TMPFILE /tmp/pass.tmp2
cat /tmp/pass.tmp2 >> /tmp/pass.tmp1
+ cat /tmp/pass.tmp2
+ 1>> /tmp/pass.tmp1
mv /tmp/pass.tmp1 /etc/passwd
+ mv /tmp/pass.tmp1 /etc/passwd


Please suggested, and it added one more line with same user id in /etc/passwd

       #include <mlib.h>

       mlib_status mlib_MatrixTranspose_U8(mlib_u8 *xz, mlib_s32 mn);

       mlib_status mlib_MatrixTranspose_S32(mlib_s32 *xz, mlib_s32 mn);

       mlib_status mlib_MatrixTranspose_S32C(mlib_s32 *xz, mlib_s32 mn);

DESCRIPTION

       Each of these functions performs an in-place transpose of a square matrix.

       For real data, the following pseudo code applies:

       for (i = 1; i < mn; i++) {
	   for (j = 0; j < i; i++) {
	       tmp	    = xz[i*mn + j];
	       xz[i*mn + j] = xz[j*mn + i];
	       xz[j*mn + i] = tmp;
	   }
       }

       For complex data, the following pseudo code applies:

       for (i = 1; i < mn; i++) {
	   for (j = 0; j < i; i++) {
	       tmp0		    = xz[2*(i*mn + j)];
	       tmp1		    = xz[2*(i*mn + j) + 1];
	       xz[2*(i*mn + j)]     = xz[2*(j*mn + i)];
	       xz[2*(i*mn + j) + 1] = xz[2*(j*mn + i) + 1];
	       xz[2*(j*mn + i)]     = tmp0;
	       xz[2*(j*mn + i) + 1] = tmp1;
	   }
       }

PARAMETERS

       Each of the functions takes the following arguments:

       xz	       Pointer to the source and destination matrix.

       mn	       Number of rows and columns in the matrix.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
