Top Forums Shell Programming and Scripting sed -i option giving error no such file or directory Post 302746995 by Scott on Thursday 20th of December 2012 10:51:31 AM
First off, please use code tags when posting code. Secondly do not post asking for help "ASAP", or I will close your thread. And thirdly your sed has an error in it. The syntax for a subsitution is s/old/new/, and lastly does the file yes.txt exist?

You are using -i. Does that require that you provide a backup filename? The man page will tell you.

SHTOOL-INSTALL.TMP(1)					      GNU Portable Shell Tool					     SHTOOL-INSTALL.TMP(1)

shtool-install - GNU shtool install(1) command SYNOPSIS
shtool install [-v|--verbose] [-t|--trace] [-d|--mkdir] [-c|--copy] [-C|--compare-copy] [-s|--strip] [-m|--mode mode] [-o|--owner owner] [-g|--group group] [-e|--exec sed-cmd] file [file ...] path DESCRIPTION
This command installs a one or more files to a given target path providing all important options of the BSD install(1) command. The trick is that the functionality is provided in a portable way. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -d, --mkdir To maximize BSD compatiblity, the BSD "shtool "install -d"" usage is internally mapped to the "shtool "mkdir -f -p -m 755"" command. -c, --copy Copy the file to the target path. Default is to move. -C, --compare-copy Same as -c except if the destination file already exists and is identical to the source file, no installation is done and the target remains untouched. -s, --strip This option strips program executables during the installation, see strip(1). Default is to install verbatim. -m, --mode mode The file mode applied to the target, see chmod(1). Setting mode to ""-"" skips this step and leaves the operating system default which is usually based on umask(1). Some file modes require superuser privileges to be set. Default is 0755. -o, --owner owner The file owner name or id applied to the target, see chown(1). This option requires superuser privileges to execute. Default is to skip this step and leave the operating system default which is usually based on the executing uid or the parent setuid directory. -g, --group group The file group name or id applied to the target, see chgrp(1). This option requires superuser privileges to execute to the fullest extend, otherwise the choice of group is limited on most operating systems. Default is to skip this step and leave the operating system default which is usually based on the executing gid or the parent setgid directory. -e, --exec sed-cmd This option can be used one or multiple times to apply one or more sed(1) commands to the file contents during installation. EXAMPLE
# Makefile install: : shtool install -c -s -m 4755 foo $(bindir)/ shtool install -c -m 644 $(mandir)/man1/foo.1 shtool install -c -m 644 -e "s/@p@/$prefix/g" foo.conf $(etcdir)/ HISTORY
The GNU shtool install command was originally written by Ralf S. Engelschall <> in 1997 for GNU shtool. It was prompted by portability issues in the installation procedures of OSSP libraries. SEE ALSO
shtool(1), umask(1), chmod(1), chown(1), chgrp(1), strip(1), sed(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-INSTALL.TMP(1)
