2. Shell Programming and Scripting
I am writing code to copy file if user dir exists.
Code snippet :
#!/bin/sh
if
then
cp ~user1/file file
else
cp ~user2/file file
fi
This code works if shell is ksh but not if shell is sh.
Can anyone suggest how this can work in sh script?

acltomode
acltomode(3SEC) File Access Control Library Functions acltomode(3SEC) NAME
acltomode, aclfrommode - convert an ACL to or from permission bits SYNOPSIS
cc [ flag... ] file... -lsec [ library... ] #include <sys/types.h> #include <sys/acl.h> int acltomode(aclent_t *aclbufp, int nentries, mode_t *modep); int aclfrommode(aclent_t *aclbufp, int nentries, mode_t *modep); DESCRIPTION
The acltomode() function converts an ACL pointed to by aclbufp into the permission bits buffer pointed to by modep. If the USER_OBJ ACL entry, GROUP_OBJ ACL entry, or the OTHER_OBJ ACL entry cannot be found in the ACL buffer, then the function fails with errno set to EIN- VAL. The USER_OBJ ACL entry permission bits are copied to the file owner class bits in the permission bits buffer. The OTHER_OBJ ACL entry per- mission bits are copied to the file other class bits in the permission bits buffer. If there is a CLASS_OBJ (ACL mask) entry, the CLASS_OBJ ACL entry permission bits are copied to the file group class bits in the permission bits buffer. Otherwise, the GROUP_OBJ ACL entry permission bits are copied to the file group class bits in the permission bits buffer. The aclfrommode() function converts the permission bits pointed to by modep into an ACL pointed to by aclbufp. If the USER_OBJ ACL entry, GROUP_OBJ ACL entry, or the OTHER_OBJ ACL entry cannot be found in the ACL buffer, the function fails with errno set to EINVAL. The file owner class bits from the permission bits buffer are copied to the USER_OBJ ACL entry. The file other class bits from the permis- sion bits buffer are copied to the OTHER_OBJ ACL entry. If there is a CLASS_OBJ (ACL mask) entry, the file group class bits from the per- mission bits buffer are copied to the CLASS_OBJ ACL entry, and the GROUP_OBJ ACL entry is not modified. Otherwise, the file group class bits from the permission bits buffer are copied to the GROUP_OBJ ACL entry. The nentries argument represents the number of ACL entries in the buffer pointed to by aclbufp. RETURN VALUES
Upon successful completion, the function returns 0. Otherwise, it returns -1 and sets errno to indicate the error. ATTRIBUTES
