Top Forums Shell Programming and Scripting Problem with loop within loop Post 302922647 by Aia on Monday 27th of October 2014 12:24:01 PM

You overwrite the PATH in the inner loop. After the first iteration of the outer loop the PATH does not contain the common locations that the shell needs to find any binaries.

Do yourself a favor and do not mess with the PATH. Certainly, it is not necessarily to change it in every iteration of the second loop. Most of the times, when the need arises, is to "add" to the PATH, but it is uncommon to completely overwrite it.
In those, cases, you use the following statement:
Code:
PATH=$PATH:/adding/new/path

NAME
gsettings - GSettings configuration tool SYNOPSIS
gsettings get SCHEMA [:PATH] KEY gsettings monitor SCHEMA [:PATH] [KEY] gsettings writable SCHEMA [:PATH] KEY gsettings range SCHEMA [:PATH] KEY gsettings set SCHEMA [:PATH] KEY VALUE gsettings reset SCHEMA [:PATH] KEY gsettings reset-recursively SCHEMA [:PATH] gsettings list-schemas gsettings list-relocatable-schemas gsettings list-keys SCHEMA [:PATH] gsettings list-children SCHEMA [:PATH] gsettings list-recursively [SCHEMA [:PATH]] gsettings help [COMMAND] DESCRIPTION
gsettings offers a simple commandline interface to GSettings. It lets you get, set or monitor an individual key for changes. The SCHEMA and KEY arguments are required for most commands to specify the schema id and the name of the key to operate on. The schema id may optionally have a :PATH suffix. Specifying the path is only needed if the schema does not have a fixed path. When setting a key, you also need specify a VALUE The format for the value is that of a serialized GVariant, so e.g. a string must include explicit quotes: "'foo'". This format is also used when printing out values. COMMANDS
get Gets the value of KEY. The value is printed out as a serialised GVariant. monitor Monitors KEY for changes and prints the changed values. If no KEY is specified, all keys in the schema are monitored. Monitoring will continue until the process is terminated. writable Finds out whether KEY is writable. range Queries the range of valid values for KEY. set Sets the value of KEY to VALUE. The value is specified as a serialised GVariant. reset Resets KEY to its default value. reset-recursively Reset all keys under the given SCHEMA. list-schemas Lists the installed, non-relocatable schemas. See list-relocatable-schemas if you are interested in relocatable schemas. list-relocatable-schemas Lists the installed, relocatable schemas. See list-schemas if you are interested in non-relocatable schemas. list-keys Lists the keys in SCHEMA. list-children Lists the children of SCHEMA. list-recursively Lists keys and values, recursively. If no SCHEMA is given, list keys in all schemas. help Prints help and exits. GIO
